Belgium technical chief Philippe Collin has urged Romelu Lukaku to leave Chelsea.

The Belgian FA have concerns over Lukaku's development while he struggles for minutes at Chelsea.

"Lukaku may need to find a club where he can play next season," said Collin.

"I'm not suggesting that it was not a good choice to go to Chelsea, but at this point the challenge for him is too much. The competition is too great, but it is understandable that he joined the club of his dreams."
