Borussia Dortmund talent Youssoufa Moukoko is becoming a hot property in the winter transfer market.

The forward, who has six months remaining on his contract, is a target for Barcelona and Chelsea.

Both clubs are serious about securing the teenager, and may even bid in the winter to steal a march on their rivals.

Borussia Dortmund chiefs Hans-Joachim Watzke and Sebastian Kehl have tried one last time to convince Moukoko to renew, per BILD in Germany.

The 18-year-old, who has netted six goals and six assists this term, is being offered triple his existing salary.

However, if he does not renew, Dortmund may have no option but to do a cut price sale in the winter.
