Chelsea have been warned by Ajax sporting director Sven Mislintat to sign Mohammed Kudus now as his price will go up in the coming weeks.

Chelsea have not yet submitted an offer but initial talks are thought to have taken place.

Speaking to Ajax Life, Mislintat admitted the club have been contacted by interested parties but are still awaiting a concrete offer for Kudus.

“There are clubs that have informally enquired about him. I don’t expect an offer very soon, although you know that things can be different in the football world,” Mislintat told Ajax Life.

“Perhaps the interest in not as serious as everyone thinks.”

“There is no fixed deadline, but there are agreements we must have to get replacements if we have not already done so proactively” he added. “Their stay or sale also depends on what we will do next.

“The best thing for is if Kudus and Alvarez stay, then we keep two top players. But it is also possible that one goes, or both.

“It is important for us that the relationship with the players remains good. This can be done by being transparent and applying good principles. As we get closer to the deadline, the transfer fee, for example, goes up.”
