Chelsea have received encouragement in their transfer pursuit of Youssoufa Moukoko.

The Borussia Dortmund teenager is in hot demand this winter and potentially in the summer.

Moukoko is out of contract when the season concludes, and the 18-year-old has not renewed his deal.

According to Bild, Dortmund have put in a final offer for Moukoko's agents to contemplate.

The deal is said to be worth £5.3 million, but there is no suggestion he will renew.

Taking to Instagram, he recently said: "Please don't believe everything that's been written in the papers.

"I won't let myself be pressured into a decision about my future. I will never accept such a lie about me.

"My full focus is on the second half of the season with Borussia Dortmund. No player is bigger than the club and I will never be bigger than the club, just a small part of it.

"It's really sad that something like that is invented just to paint you fans a wrong picture about me. I am really shocked by this story."
