Jonathan David
The Lille star played at home and away against Chelsea in last season’s Champions League play-offs. As such, Thomas Tuchel met the 22-year-old up close and personal, who is a regular feature on the charts of the best clubs in Europe.
Although he failed to score in any of these qualifiers, he scored 19 in all competitions last season, which is a constant improvement on his first campaign in League 1. With a lot of potential yet to be unblocked, the blues may have to pay around £. 40 m for David if they want to join the transfer hunt.
