Chelsea striker Michy Batshuayi has been warned he's set himself a high standard at Borussia Dortmund.

Batshuayi scored twice for his loan club on debut in victory over FC Koln last Friday.

BVB coach Peter Stoger can understand expectations are high from fans for the Belgium international.

"He is naturally in a good mood, and in good shape. Expectations are necessarily huge after both goals," smiled Stoger.

"I expect him to continue playing well."
