The 25-year-old was expected to leave United earlier this season after refusing to sign a new deal with the club.
Rooney finally signed a five-year contract with the Red Devils.
“I’ve always wanted to be at this club,” Rooney told MUTV.
“I had my concerns and voiced my opinion but I was delighted to sign long term.
“I want to help the young players like Giggsy [Ryan Giggs], Gary Neville and Scholesy [Paul Scholes] helped me.”
Rooney insists he was happy with the fans’ reception when he made his return to action from an ankle injury as a substitute in last week’s home win against Wigan.
“I’d be lying if I say I wasn’t worried about the fans’ reception but it was brilliant,” he said.
“I can understand the fans’ frustration with the negotiations and it happened in the public eye which made it a little bit more difficult but I think the main thing for myself and the club is that we managed to agree that deal.
“I’ve heard from different press people about how I’ve agreed a new deal so the club can agree a higher price with a different team which is a load of rubbish. I’ve signed a deal to stay and my long-term future is at Manchester United.”
