The agent of Youssoufa Moukoko has offered encouragement to Chelsea and Manchester United in their pursuit of the Borussia Dortmund striker.

Negotiations over a pre-contract agreement can begin in January, six months before he becomes a free agent.

Moukoko's agent, Patrick Williams, has spoken out on the interest in Moukoko as talks continue with Borussia. He also denied that the youngster is seeking a huge pay rise, with rumours saying a £115,000 weekly wage being demanded.

He told Sky Deutschland: “I can confirm that we are not about to conclude a contract extension with Borussia Dortmund.

“I can also assure you that the numbers that are circulating are simply not correct and Youssoufa was never offered that much. But we are still in contact with Dortmund and will see what the next few days bring.

“A player like Youssoufa is interesting for every top club in the world. Especially when he is free and has a future in the German national team."
