Timber was one of Ten Hag’s top targets and Manchester United discussed personal terms with his representatives over taking him to Old Trafford.
But the 21-year-old defender decided against moving to Manchester United with suggestions that he was afraid that he could lose his place in the Netherlands squad for the World Cup.
It has been claimed that Van Gaal played a key role in keeping Timber at Ajax with the threat of not selecting him if he was not a regular at Manchester United.
However, Vink stressed that the Netherlands manager has conceded that he cannot ignore players if they are not playing regularly while stopping Timber from joining Manchester United.
He said on ESPN Netherlands: “I find that incomprehensible.
“He indicated that he can no longer refuse to select players if they are not playing.
“Now he gives Timber a reason to stay with Ajax because that chance that he plays regularly at United will be smaller.
“Then I think that’s a bit contradictory.
“On one hand you force the boy to stay at a club and make a wise choice but on the other hand, you shout from the rooftops that you don’t care if someone plays regularly at their clubs.”
He conceded that if he was in Ten Hag’s position he would have been annoyed that the Dutch national team manager got involved in order to stop him from getting a player for Manchester United.
“If I was Ten Hag, I would be annoyed.
“Timber would have been a key player at United and the game they want to play, together with Frenkie de Jong.
“I would understand his frustration, I would find it difficult if the national coach gets involved.”
