Chelsea have pre-agreement to sign Christopher Nkunku

Chelsea have finalised a pre-agreement to sign Christopher Nkunku next summer, according to journalist David Ornstein.

The Blues are long-term admirers of the France international and earlier this summer, the Frenchman had a secret medical with them.

It is now reported that they have agreed to sign the RB Leipzig star. His €60m release clause becomes active next summer, but the Blues will pay more.

The west London giants have been pro-active since Todd Boehly became their owner and they are looking into young signings for long-term success.

Nkunku at 24 is a wonderful acquisition for the Blues and the club also appear determined on prising away his Leipzig teammate Josko Gvardiol.

They were unsuccessful in negotiating a pre-agreement for the Croatian last month, but are expected to try again, according to The Telegraph.

Chelsea recently returned to winning ways in the Premier League with a 2-1 comeback triumph over London rivals Crystal Palace on the road.

They will be in Champions League action against AC Milan in midweek.
