Louis van Gaal believes that Frenkie de Jong made the wrong decision in signing for Barcelona due to the midfield competition at the club.

Van Gaal added that de Jong is at the age where he has to play, but a place is not guaranteed on Ernesto Valverde's side.

"I think it will be difficult for him there. Not only because he'll have a different role there, but because he'll be competing with others to make the starting eleven...In my opinion, he could have chosen better. De Jong is a very good player, but so is Ivan Rakitic, and five years ago when I was at Manchester United, I wanted to sign Arturo Vidal. As a player you always have to choose a club where you can play. The question is, does he have this assured at Barcelona, we'll have to wait and see, I hope so because at that age you have to play every game," said van Gaal.
