Arsenal hero Jens Lehmann can't explain the form slide of Jadon Sancho at Borussia Dortmund.

Lehmann is also a former BVB goalkeeper.

When quizzed on whether the Manchester United transfer saga over the summer has affected Sancho's performance levels, he told the Daily Mail: "I don't know if that's true.

"I only know that the hype has come down a little because now Haaland is playing for Borussia.

"And he is a beast I can tell you, he is fantastic. Unfortunately he is injured right now, but when he plays he is like a train, he goes forward very fast. He took on the hype of Sancho."
