Premier League clubs are circling Bayer Leverkusen for Jonathan Tah.
The Germany defender is interesting Fulham, Arsenal and Leicester City ahead of next month's transfer deadline.
And Bayer are prepared to sell after Tah lost his first-choice status last season.
Bayer sports chief Simon Rolfes said this week: "He's also a player who can improve. I trust him to play a much better role and take a step forward.
"(But) we cannot exclude anything (regarding a move away)."
