Manchester United, Liverpool and Chelsea have been given hope in their pursuit of Ajax midfielder Donny Van de Beek.
The 21-year-old's agent has expressed his dissatisfaction with his current club situation and has suggested a transfer might be the only solution.
"It is true that this interest has been there for a while," Guido Alberts told Voetbal International
"Last summer it was already concrete, but Donny opted for a longer stay at Ajax.
"The past few months have gone differently than we had in mind.
"If his situation remains the same way for much longer, a transfer is a better option for all parties.
"These agreements have now also been made with [director of football] Marc Overmars.
"If the situation remains the same, a transfer can be discussed."
