THIS IS WHY CHELSEA HAVE NOT YET SIGNED TIEMOUE BAKAYAKO?

There was a lot of talk that Chelsea was going to sign up with the French midfielder from Monaco Tiemoue Bakayoko . But it is quite some time since it was confirmed or rejected. And in the middle it was said that Manchester United wanted to hijack the deal as the Nemanja Matic deal is now stalled. But it appears that the midfielder indeed did undergo a minor surgery at the end of the last season, and he will be coming to Chelsea for a full medical , even if there is a scare for them. But another story says that Monaco are not happy with the 37,Chelsea increased to, but they want 40, forty million pounds plus add ons.
