RB Leipzig striker Christophe Nkunku has suffered a new injury setback.

Nkunku, who will join Chelsea this summer, pulled up during defeat to Borussia Dortmund yesterday.

The Frenchman "noticed something in the muscle during a sprint". Nkunku is only just back from tearing his lateral ligament which cost him his place at the World Cup with France. Against BVB he started for the first time since his injury recovery.

“You play here in Dortmund and you really want to win the game," said RBL coach Marco Rose.

"In the end I think I should have done better and taken him out sooner. Now we have to bear the consequences."
