The German press writes, on Monday, that Chelsea have already agreed to hire Christopher Nkunku for next season.
According to the German newspaper Bild, the London team will trigger the release clause, worth €60 million, to secure the services of the 24-year-old French winger, which will only come into force next summer.
The same source stresses that the deal will be announced in the coming weeks, as Nkunku has already completed a medical for Chelsea at the end of August.
The French international, André Silva's teammate, has scored eight goals and provided an assist in 12 games for Leipzig this season.
