Borussia Dortmund sporting director Sebastian Kehl admits they're delighted with Jadon Sancho's return.
The Manchester United winger has re-signed for United after two years away on-loan to the end of season.
Kehl said: "Sancho is a player who makes the difference and I can't wait to see him on the pitch again in our shirt.
"He knows this city, Signal Iduna Park, our fans and our club.
"Even though he has not played any official matches in recent months, we are sure he will quickly adapt to the team, get into shape and help us achieve our goals for the season with his qualities."
