The Monaco midfielder has agreed terms with the Premier League champions after delays over his fitness and intermediaries
Tiemoue Bakayoko's protracted transfer saga with Chelsea appears close to an end after all three parties come to a final agreement on Wednesday ahead of a £40 million exit from Monaco.
The Blues had long since arranged an agreement with the Ligue 1 champions, as well as a wage for Bakayoko, but had struggled to organise a medical due to concerns over the midfielder's fitness.
The club have been cautious to avoid signing a player with any long-term injury concerns, but they are satisfied that he can complete a medical even after having had minor surgery on his knee.
