Belgium coach Marc Wilmots says Adnan Januzaj will have it all to prove at Borussia Dortmund.
The Manchester United winger joined BVB on-loan for the season yesterday.
Wilmots commented: "At Manchester United, it is difficult to get a starting spot, that's for sure.
"But there is very little difference between the German league and the Premier League. Borussia Dortmund is at the moment a team of a very high level.
"We have not spoken to each other about the transfer."
