Wesley Fofana has become the latest player to join Chelsea and conclude Thomas Tuchel’s search for defensive reinforcements.
The France Under-21 international joins from Leicester for a reported fee of around £70million, becoming one of the most expensive defenders in history.
The centre-back, who played only seven times last term due to a broken leg, has signed a seven-year deal at Stamford Bridge.
