Chelsea, Liverpool and Manchester United target Leon Bailey says there is no guarantee that he will stay at Bayer Leverkusen beyond the end of the current season.
Bailey has been in phenomenal form this season, scoring ten goals and providing five assists in 19 appearances.
It is already the most productive season of his professional career, having broken through with Genk in Belgium in 2015.
He joined Leverkusen in 2017 after warning United that he would not join if he would not be afforded regular minutes.
The wide forward remains a target for United, with Chelsea and Liverpool also linked in recent weeks.
The 20-year-old will not be moving to the Premier League this winter, but offered no promises to stay in Germany beyond May.
“I can promise I will stay at Leverkusen this season,” Bailey told Sky Germany.
“Who knows what will happen in the future?”
