#4 Manchester City
Player: Riyad Mahrez
Transfer fee: £60 million
Bought from: Leicester City

Riyad Mahrez was an integral part of the title-winning Leicester City side and is considered one of the best players in the Premier League. Manchester City bought the 28-year-old last summer and he has turned out to be a quality acquisition to Pep Guardiola’s side. He has struggled for minutes this season with Raheem Sterling and Leroy Sane fighting for the same spot but has chipped in with some important goals this season.
#3 Chelsea
Player: Kepa Arrizabalaga
Transfer fee: £71 million
Bought from: Athletic Bilbao

Chelsea had to splash £71 million to lure Kepa from Athletic Bilbao in order to replace Thibaut Courtois. The 24-year-old has been ever-present in goal for Chelsea this season, making 43 appearances across all competitions. His refusal to get off the pitch during the EFL Cup final caused a lot of controversies and earned him a lot of criticism from fans and pundits. But otherwise, he has been brilliant between the sticks for Chelsea this season.
