Red Bull put their foot down over £87m Yan Diomande deal

Diomande won't be sold easily

And he had a big warning to Liverpool and indeed every other club interested in Diomande this summer. According to Mintzlaff the young African superstar won’t be going anywhere.

"I can say: If I were sporting director, I wouldn't sell this young player, who hasn't even completed a full season with us,” the Red Bull exec disclosed as per BILD.

“No matter what price is being asked. I believe he's a player who can still develop further, because he's still very young. And he can certainly become more expensive.

“Of course, there are other clubs where players also want to take the next step – FC Bayern is one of them, but also clubs from England and Spain.

“But we have to expect that a player, even if he delivers outstanding performances here, doesn't leave again after just one year.

"Therefore, I can only recommend to the management that they keep this player with us for the coming season. And then we'll have to see how he develops.”

Leipzig want to see Diomande in the Champions League

Leipzig have got big plans to return to Champions League football for next season and they believe it will provide a shop window for Diomande.

“We want to play in the Champions League,” Mintzlaff said.

“And that's naturally an argument for such a young player, to then deliver what he's shown in a second season and potentially develop further – also at an international level.

“So we have many good arguments. And the best argument is a long-term contract. Therefore, I'm completely relaxed about the whole matter.”
