10. Islam Slimani: Sporting CP to Leicester (2016) – £29m
Following Leicester’s shock Premier League title win in 2015/16, the Foxes needed to bring in reinforcements ahead of their maiden Champions League campaign, with Islam Slimani proving to be the costliest of the lot.
Signing from Sporting CP in 2016 for £29m, the Algerian international was seen as an alternative to the pace of Jamie Vardy, but a record of 13 goals in 46 appearances suggests the outlay is yet to be warranted.
A loan to Newcastle in January 2018 highlighted where Slimani was in Leicester’s pecking order, although four appearances without a goal in a injury-hit time in the north east hardly proved the doubters wrong.
9. Moussa Sissoko: Newcastle to Tottenham (2016) – £30m
Seemingly set to join Everton following Newcastle’s relegation from the Premier League in the 2015/16, Mauricio Pochettino made a late offer to sign the Frenchman, paying £30m to bring Sissoko to Tottenham.
After starring for France at Euro 2016, Spurs fans were hoping to see that Sissoko; yet instead, they signed a woefully inconsistent player who has struggled justify the fee paid by Pochettino two years ago.
With one goal and one assist in 33 league appearances last season, the 28-year-old will continue to struggle for regular game time next season, while Spurs may struggle to offload the misfiring French international.
8. Christian Benteke: Aston Villa to Liverpool (2015) – £32.5m
Averaging nearly a goal every two games at Aston Villa, Liverpool decided to spend £32.5m to bring Christian Benteke to Anfield following the sale of Raheem Sterling to Manchester City.
Offering a physical focal point for Brendan Rodgers’ side to work from, the Belgian international failed to settle on Merseyside, scoring just ten goals in 41 games during the 2015/16 campaign.
The following summer the striker was on the move once more – after Jurgen Klopp made it clear he was not part of his plans for the club – joining Crystal Palace for a staggering £32m.
7. Andy Carroll: Newcastle to Liverpool (2011) – £35m
Following the departure of Fernando Torres to Chelsea, Liverpool had £50m to spend on assembling a new strike force, and while the signing of Luis Suarez proved to be a hit, Andy Carroll was definitely a miss.
Signed for a then club-record £35m in January 2011, Carroll’s career at Anfield never got going. Form and injuries meant he was more of a burden then the strong target man Liverpool signed him to be, with his 11 goals in 58 games for the Reds suggesting that.
Liverpool eventually offloaded the forward, initially on loan to West Ham, before agreeing a £15m deal with the Hammers, where his injury problems still persist.
6. Granit Xhaka: Borussia Monchengladbach to Arsenal (2016) – £35m
Signed in the summer of 2016, Arsenal staved off apparent interest from Bundesliga giants Bayern Munich to sign Granit Xhaka; the German club may now think they’ve dodged a bullet however.
The Swiss international has failed to impress during his two seasons in the Premier League, with his rash tackling and positional naivety the source of criticism for a man signed to be the defensive midfielder Arsenal had been crying out for.
An estimated £35m is what Arsene Wenger had to spend to sign Xhaka, yet while the 25-year-old does have time on his side, he looks a long way off from validating his price tag.
5. Shkodran Mustafi: Valencia to Arsenal (2016) – £35m
A panic buy towards the end of the transfer window in August 2016, Shkodran Mustafi came in to help sure up Arsenal’s leaky defence, but has since become part of the problem.
Looking an erratic figure at the heart of the Gunners’ defence for the past two seasons, even the most fervent Mustafi fan will find it hard to say that the £35m Arsenal spent to sign the German international was money well spent.
Following the appointment of Unai Emery at the club, who has bought Sokratis from Borussia Dortmund to improve the defence, the World Cup winner has been linked with a move away; although Arsenal may find it difficult to recoup the full £35m for him.
4. Danny Drinkwater: Leicester to Chelsea (2017) – £35m
Completing a deadline day switch from Leicester to Chelsea in August 2017, the £35m fee that the Blues had to pay to sign Danny Drinkwater left many bemused.
Despite playing an integral part in the Foxes’ Premier League title win in 2015/16, the midfielder failed to recapture the form the following campaign, which made his move to Antonio Conte’s side all the more surprising.
Reduced to a role of squad player, the 28-year-old only made 12 appearances in the league last season.
3. Gylfi Sigurdsson: Swansea to Everton (2017) – £45m
After helping Swansea avoid relegation from the Premier League in 2016/17, with his nine goals and 13 assists helping keep the Welsh side in the division, a move seemed inevitable for the Icelandic international, although the transfer fee came as a shock.
Chased by Everton throughout the majority of that years transfer window, Ronald Koeman eventually got his man, with the Toffees having to part with £45m in order to do so. His form in 2017/18 failed to justify the price tag.
As Everton struggled, so did Sigurdsson, with his four goals and three assists in the league not exactly the return from a man who was their record signing prior to the expected arrival of Richarlison.
2. Fernando Torres: Liverpool to Chelsea (2011) – £50m
Earning a fearsome reputation as one of the world’s most potent strikers at Liverpool, Chelsea forked out a British record £50m in order to sign the Spaniard in 2011.
After scoring 65 goals in 102 Premier League appearances for the Reds, fans of the Blues were expecting big things from the former Atletico Madrid star. However, Torres failed to justify the transfer fee during his time at Stamford Bridge.
His 45 goals in 172 appearances for Chelsea was hardly befitting of a player price at £50m, with Torres looking a shadow of his former self, resulting in a move to AC Milan in 2015 for just £2.7m.
1. Angel Di Maria: Real Madrid to Manchester United (2014) – £59.7m
Upon helping Real Madrid to a Champions League and Copa Del Rey double in 2013/14, Manchester United decided to break the British transfer record to sign Angel Di Maria for £59.7m.
Yet despite the extortionate price tag and the odd moment of magic such as the stunning chip against Leicester, Di Maria failed to adapt to life in England, as Louis van Gaal opted to play the Argentine as a winger, despite flourishing in a central role for Los Blancos.
After one season in the Premier League, Di Maria swapped England for France, signing for Paris Saint-Germain in a deal worth £44.3m, as the former SL Benfica man failed to leave his mark for the Red Devils.
