Ajax midfielder Donny van de Beek is staying grounded over increased speculation of a January move away.

The youngster is being linked with AS Roma this week, while he has also been watched by Chelsea, Manchester United and Liverpool this season.

"I am very happy at Ajax. Do I still play here after the winter? I'll assume that, for sure. I still have enough to achieve and to achieve here," said Van de Beek.

"I know what you are referring to, but I am not at all concerned with it. I am busy with Ajax.

"I cannot do much about it. There are super-important matches with Ajax and I focus on that. I'm not busy with all those other things."

Van de Beek's current deal runs to 2022.
