Borussia Dortmund youth chief Lars Ricken admits foreign interest is intensifying for young striker Youssoufa Moukoko.

The 13 year-old prospect is making a buzz across Europe, with the likes of Real Madrid, Barcelona, Manchester United and Manchester City all keen to tempt him from Dortmund.

"The boy is very clear in the head," Ricken told Kicker, "despite the already extensive coverage of him, he runs with a smile on the training grounds.

"Of course, with every top talent the clubs from abroad are in the race. This is a national and international competition.

"Before he is 17, he cannot play in the pros. That's why nobody has to panic because of him today."
