Van de Beek, 24, completed a £40million move to Old Trafford last summer from boyhood club Ajax.
The midfielder thrived at Ajax, making 175 appearances for the club and helping them win the Eredivisie and reach the Champions League semi-finals in 2019.
Van de Beek has been unable to transfer that form to the Theatre of Dreams, however, starting just four of Manchester United’s Premier League fixtures during the 2020-21 campaign and scoring just once in 36 matches in all competitions.
Former Ajax and Netherlands forward Van der Vaart doubts Van de Beek has a future at Old Trafford and says he should have joined ‘a club like’ Borussia Dortmund instead in 2020.
‘He fit perfectly into the Ajax system, but he doesn’t fit at Manchester United,’ Van der Vaart told ESPN.
‘If nobody leaves United [this summer], he will be lucky to get in the starting line-up.
‘He is far too good to sit on the bench for two seasons. He needs minutes very quickly. He is still young, but time flies.
‘A club like Borussia Dortmund would have been a better step for him. Manchester United might be a step too far for him.’
Speaking last month, another ex-Ajax and Netherlands star – Marc Overmars – urged Van de Beek to ‘fight’ for his place at Manchester United.
‘I think Donny should just fight, stay next year and try to claim a starting place,’ Overmars told NOS. ‘You shouldn’t leave so quickly.’
