Van de Beek made the switch to Old Trafford from Ajax earlier this week despite Barcelona having been considered frontrunners in the race to sign as recent as last weekend.
The La Liga giants are determined to improve their midfield with new boss Ronald Koeman eager to put his mark on the squad.
Ivan Rakitic has left the Nou Camp while Arturo Vidal is also expected to depart this summer.
But Spanish outlet Mundo Deportivo claim Barcelona weren’t overly fussed about Van de Beek’s switch to Manchester United.
The 23-year-old penned a five-year contract with United, with an option for another year.
On signing for the Red Devils, he said: “In my career it’s a good time to make a step to a nice club.
“I think I have made a really good decision to join this amazing club. I cannot explain [how I feel].
“I have heard all the stories from the old players, including Edwin [van der Sar], our old director, and Daley Blind, my old team-mate, and I cannot wait to play for the club.
"Always when people tell you something about the Premier League, they tell you it’s really strong with heavy competition. I will see that.
“I want to work on my physicality, on everything, to make steps again, because for Holland I was strong and physically good, but now I want to make steps again to improve and help the club get prizes and titles.
