The Ajax boss has questioned the Red Devils' use of a man that emerged as one of the top young players in Europe at Johan Cruyff ArenA
Ajax manager Erik ten Hag has accused Manchester United of committing a "mortal sin" with their treatment of Donny van de Beek.
United invested £35 million ($46m) in Van de Beek's talent in September 2020, prising him away from Ajax on a five-year contract.
The Dutchman was initially heralded as a stellar signing after his rapid rise to prominence at Johan Cruyff ArenA but has found regular opportunities hard to come by at Old Trafford, much to the bemusement of Ten Hag.
