Thomas Tuchel's influential role in Chelsea's transfers might have earnt him the biggest transfer coup of the summer.
Despite having already secured deals for Kalidou Koulibaly and Raheem Sterling, two immediate first team players with top level experience, world class mentalities and quality technical ability, the best signing of the summer could be that of 18-year-old Carney Chukwuemeka from Aston Villa.
The Blues announced that they had agreed a deal with Steven Gerrard's side for the player out of the blue and in a deal that is worth just £20m, and only with £10m up front, it is a bargain.
