#3 Idrissa Gueye
In one of Aston Villa’s worst seasons in history, perhaps the only silver lining was the performance of this Senegalese midfielder throughout their relegation campaign. Everton saw that, and they bought Gueye for £7.1 million in a deal which could be argued is the bargain of the season so far.
Defensive midfielders often do not get the credit they deserve, but Gueye’s performances have earned him praise from fans and experts alike, who are now wondering as to why some other club did not go for him.
Having settled at Goodison Park in a matter of few games, the 27-year-old has made the most tackles (66) in the league so far - nine ahead of his closest competitor. Averaging an astonishing 5.2 tackles alongside 2.1 interceptions per game, and with a passing accuracy of 87%, Gueye has been a rock in the Everton midfield.
Koeman’s team is currently 8th in the Premier League and although they could be doing better, they have Gueye to thank for where they are now, as it could have been worse without the presence of the ex-Aston Villa man. A true bargain, Gueye is also the cheapest transfer on this list.
