It's been reported since the last transfer window though that nkunku willing to move to premier league side like chelsea and manchester united but the club stated that going to reject any proposal coming to them but this time the rumor seems a bit different.
Chelsea might have an insider agent that could make this transfer happened despite the long term contract.
There is some information circulating right now but it looks like this will continue to provide a sensation until the transfer window opens.
At the moment he still hasn't spoken much in these rumours and some of Nkunku's closest people have said that at the moment there is still no agreement whatsoever about him and Chelsea or any club.
Nkunku himself has a release clause of 60 million depending on who dares now because at the moment there are several clubs and of course Manchester United and Chelsea are the frontrunners.
