Crystal Palace – Marc Guehi (€40m)
The £18m that Crystal Palace paid Chelsea for the centre-back two years ago seems like a bargain now.
Guehi is a leader for the Eagles, despite his young age, and he has formed a good partnership with Joachim Andersen in the centre of the Eagles’ defence.
He is being scouted by a number of other Premier League clubs, including Arsenal, Manchester United and Liverpool.
It would, therefore, not be a surprise if he leaves Selhurst Park this summer.
