Bayer Leverkusen have warned Chelsea, Manchester United and Liverpool their star winger Leon Bailey is not for sale.

Bailey is only 21, but a host of top Premier League clubs are chasing after his signature.

And Goal.com reports that despite the likes of Man City also having an interest, he will not be going anywhere.

Leverkusen have said as much themselves.

"We all know that Leon will eventually go, but we have made it clear that a winter change is out of the question, and he also knows that he has our backing," sporting director Jonas Boldt told Bild.
