5. Leicester City – Riyad Mahrez – A close call between Mahrez and Jamie Vardy, but the Algerian edges it considering he cost just £400,000 and was the PFA Premier League Player of the Year last season. He, alongside NGolo Kante and Vardy, was the driving force behind Leicesters 2016 shock title triumph, scoring 18 goals and setting up 10 in 39 appearances. Mahrez signed a well-deserved five-year contract last summer and, while his performances this season have not been to the high standard we have come to expect, his ability is clear to see. Leicester could make quite the profit once they decide to sell the 26-year-old. 9. Stoke City – Jack Butland – Stoke City beat a number of Premier League suitors to Jack Butlands signature when they bought him from Birmingham City for around £4m in 2013. Already an England international, hopes were high and, after a number of loan spells in the Championship, he was handed the number one shirt in the wake of Asmir Begovics departure to Chelsea. He has impressed between the sticks for the Potters and is expected to rival Joe Hart for the Three Lions number one spot for years to come. Butland is just returning from a year on the sidelines with an ankle injury and it will be difficult to displace Lee Grant, but he is a quality shot-stopper and is certainly a bargain buy. 20 20 2. Liverpool – Philippe Coutinho – Not many top teams in the Premier League can claim their star player cost less than £10m, but the Merseysiders can. The Reds signed Coutinho from Inter Milan for around £8.5m in 2013 and what a deal that has proved to be. The Brazilian playmaker is the one Liverpool turn to when they need a moment of magic and he often produces. When Coutinho is on song, so is the team and Jurgen Klopp will be desperate to keep hold of him, amid interest from Barcelona. He has scored 38 times and set up 36 goals in 176 appearances for Liverpool. Still only 24 years old, he signed a new five-year deal in January. 3. Tottenham Hotspur – Danny Rose – The England left-backs performances have been on a different level this season, making him one of the best in the world in his position. He is excellent defensively and a threat going forward, scoring two goals and assisting four in 21 appearances this season. He has not played since the end of January due to injury and could make his return in the north London derby with Arsenal. He joined Spurs from Leeds shortly after his 17th birthday for around £1million and has since made nearly 150 appearances for Spurs. He has been linked with a £50m move to Manchester City in recent months, despite penning a new long-term deal in September. 16. Sunderland – Jermain Defoe – Seb Larsson goes close after joining on a free transfer from Birmingham City in 2011. But Defoe arrived on Wearside in 2015 in a reported £14m deal, which included Jozy Altidore in exchange, and twice fired the Black Cats to Premier League safety, when on both occasions they looked destined for the drop. His fee was justified after saving the club more money by keeping them in the top flight and without his goals this season they would be even further adrift at the bottom of the table. The 34-year-old was deservedly rewarded with a return to the England fold, scoring on his comeback in March. He has scored 36 goals in 88 Sunderland appearances and will undoubtedly have options in the summer. He may not come cheap, though, after penning a new deal last year. 20 10. Watford – Troy Deeney – The striker arrived at Vicarage Road in a £500,000 deal from Walsall in 2010 and, now captain, is considered a Watford legend. He attracted the interest of Premier League champions Leicester City last summer and has recently fallen out of favour under Walter Mazzarri, but he told talkSPORT this week: If Watford want to keep me, Im happy to stay. He formed a deadly partnership with Odion Ighalo in the Championship and the first half of last season. His Watford record reads 106 goals and 49 assists in 297 appearances. 7. Chelsea – Thibaut Courtois – To be able to displace Petr Cech from his spot as first-choice goalkeeper at Stamford Bridge, you must be something special. The Blues signed 19-year-old Courtois from Genk for a reported £7.9m in 2011 and he was immediately loaned to Atletico Madrid, who had just lost David De Gea to Manchester United. He spent three successful seasons in the Spanish capital winning LaLiga, the Europa League and playing in the Champions League final before returning to Stamford Bridge. He was Jose Mourinhos first choice ahead of Cech for the 2014/15 campaign as the Blues won the title. The 24-year-old recently made his 100th appearance for the west Londoners and could occupy the position for the next decade at least. 20 20 19. AFC Bournemouth – Josh King – Weeks after sealing promotion to the Premier League, Bournemouth signed Josh King after the Norwegian rejected the offer of a new contract from Blackburn. The Cherries later agreed a compensation fee, reported to be around £1million, as he was under the age of 24. He scored seven goals and assisted four more in 35 appearances during his first season on the south coast. This year he has nearly doubled that goal tally, having scored 10 times in his last 12 appearances, including a hat-trick v West Ham in March. He has helped ease the loss of Callum Wilson to injury, improving each season and helping Eddie Howes side to establish themselves in the top flight. 20 13. Southampton – Oriol Romeu – When it became clear Romeu would not break into Chelseas first team on a regular basis, Southampton paid the west Londoners £5m for his services in 2015 and what a coup it has proved to be. The former Barcelona midfielder has even attracted the interest of the LaLiga giants after a strong campaign on the south coast. He breaks up play in the centre of midfield and has helped Claude Puels side tick this season. 20 20 12. Arsenal – Laurent Koscielny – The Frenchman was relatively unknown when Arsenal signed him from Lorient for around £8.25m in 2010. After going five seasons without silverware, and with William Gallas, Mikael Silvestre, Philippe Senderos and Sol Campbell on their way out of the club, Arsene Wenger was in need of defensive reinforcements. The deal completed a remarkable rise for Koscielny, who had been playing in Ligue 2 the year before. He has since formed partnerships with Per Mertesacker and this season Shkodran Mustafi, often captained the Gunners and won two FA Cups. The 31-year-old has made 285 appearances and was rewarded with a new long-term contract in January. 20 20 20 20 17. Crystal Palace – Joel Ward – After their relegation from the Championship in 2012, a whole host of players left Portsmouth, including Joel Ward. He moved to Selhurst Park when the Eagles were still in the Championship for a reported £400,000, easing the loss of Nathaniel Clyne to Southampton. Ward has impressed in the right-back role, making 180 appearances, brilliantly adjusting to the Premier League, and he was rewarded with a new deal in 2015. 18. Hull City – Sam Clucas – The midfielder earned a move to Hull City – then in the Championship – for around £1.3m after his eye-catching performances for Chesterfield in 2015. His debut season in the Premier League has been impressive, completing an impressive rise to the top. In 2009, Lincoln-born Clucas was working in a cafe in Debenhams earning £6.20 per hour, now he has completed the feat of playing in Englands top five divisions in five consecutive seasons [with Hereford, Mansfield, Chesterfield and Hull]. Even if Hull fail to beat the drop, the 26-year-old will not be short of options. His versatility he can play left-back, left midfield and central midfield makes him a useful asset to have. Clucas can be considered a bargain, although he is closely rivalled in Hulls ranks by Harry Maguire and Andrew Robertson, who have promising futures ahead of them. 20. Middlesbrough – George Friend – click the right arrow, above, to see our ranking of each Premier League club’s best bargain buy… – Boro made a move to sign Doncasters captain, Player of the Year and Players Player of the Year in 2012 for around £100,000 and it has proved to be great business. He has struggled with injury setbacks this term, restricting him to just 18 Premier League appearances, but he has been impressive for the Teessiders and is closing in on his 200th match in a Boro shirt. He was deservedly rewarded with a new four-year contract after helping the club to promotion to the top tier in 2015/16. 6. Burnley – Tom Heaton – Sean Dyche pulled off a masterstroke after signing Heaton from Bristol City on a free transfer in 2013. Four years, 169 appearances and 59 clean sheets later, Heaton is an established goalkeeper, making the position his own at Turf Moor and he is now a regular in the England squad. He signed a new four-year contract last summer and was linked with a move to Everton this year after impressive performances which have helped Burnley retain their top-flight status. 14. West Bromwich Albion – Jonny Evans – Although Darren Fletchers free transfer nearly made it as West Broms best bargain buy, Jonny Evans edges it after being a rock at the back for Tony Pulis side this season. The Northern Ireland defender is a key reason the Baggies occupy eighth place. He has played 26 times in the Premier League this term and the £6m fee paid in 2015 looks quite the steal. 11. West Ham United – Aaron Cresswell – The full-backs season has been disrupted by injuries but the £2m fee paid to Ipswich in 2014 has proved to be value for money. He instantly made the step up and has impressed, making the left-back spot his own when fit. Cresswell has made 119 appearances for the Hammers and was rewarded with a contract extension last summer, amid reported interest from big clubs, keeping him in east London until 2021. 20 20 20 20 Everybody loves a bargain.We have seen some crazy amounts of money questionably shelled out for players in the Premier League, but we have also seen some brilliant deals done over the years.talkSPORT has taken a look at each top-flight club’s current squad and selected the best bargain in their ranks.Click the right arrow, above, as we rank some of the most impressive purchases and comment below if you disagree – remember they still have to be playing for that club…READ MORE: Controversial Premier League transfers between rival clubs, including Campbell, Tevez and Cole 20 20 20 15. Swansea City – Fernando Llorente – Eyebrows were raised when Swansea shelled out £5m to sign a 31-year-old striker from Spain. He previously had a good record with Athletic Bilbao and Juventus in previous years, but his Sevilla statistics did not make great reading. He has been key for the Welsh side this term so much so Chelsea were interested in signing him in January. He has scored 11 goals in 30 appearances in all competitions this season, despite the uncertainty off field [playing under four different managers, including caretaker Alan Curtis] and he has helped them remain within a chance of Premier League survival. If the Jacks cannot avoid the drop, Llorente will probably still get a move. 4. Everton – Seamus Coleman – The £60,000 fee paid to Sligo Rovers for Coleman in 2009 looks an absolute steal. The Republic of Ireland captain currently out of action with a double leg break is now a key player at Goodison and has racked up nearly 250 appearances in a Toffees shirt. His tireless work-rate makes him a hit with the fans and his versatility means he can occupy a number of positions. 8. Manchester United – Zlatan Ibrahimovic – Although United may shell out over £250,000-a-week for the Swedish forwards services, signing him on a free transfer was great business by Jose Mourinho. He arrived months before his 35th birthday and many questioned whether he would be past it. But 28 goals and 11 assists later for the Red Devils, he has answered those critics. So much so, the club are keen to extend his stay at Old Trafford, amid reported interest from MLS side LA Galaxy. 20 1. Manchester City – Vincent Kompany – The Citizens paid in the region of £6m to sign the Belgian from Hamburg in 2008 and he will undoubtedly go down as a club legend. In an era of huge sums being spent City, Kompany is easily their best bit of business. Although he has had a tough couple of seasons due to injury, Kompany has been an exemplary leader, playing a key role in securing two Premier League trophies, two League Cups and an FA Cup win. Kompany has made over 300 appearances in a sky blue shirt, put in some world-class performances and been a key part of the City revolution.
