RB Leipzig coach Marco Rose has confirmed they'll lose Christopher Nkunku to Chelsea this summer.

The striker signed for Chelsea before Christmas and has just returned to action from knee injury.

Nkunku scored the winner against Hoffenheim on the weekend and Rose enthused: "That (the winning goal against Hoffenheim) should give him a boost in the next few weeks - for his last weeks with us."

Nkunku has scored 18 goals and provided five assists in 30 competitive games for Leipzig this season.
