Maguire has endured a challenging start to the campaign. United have fallen down to 12th in the Premier League, despite making Maguire the most expensive defender in history to try and solve their defensive struggles.
Speaking to Inside United, Maguire reiterated his determination to succeed at Old Trafford, calling of fans to be patient with the process at the club.
He said: “I think its the long term, thats what the main thing is. In five or six years time, judge me then - whether I have been a success at this club or not.
“And I do believe and am really confident that, in five or six years’ time, I’ll be a success and I am sure we’ll have many, many good times here.”
There have even been claims that Maguire has struggled with the pressure of his price tag. United spent a huge £80m to lure him away from Leicester City during the summer, but Maguire has insisted that he has never been concerned about the pressure that comes with making such a move.
“No, it doesnt bother me at all. Its something that I cant affect. Leicester wanted to keep me and they are in a great position as a club," Maguire added.
“Manchester United wanted to buy me and they came to an agreement. Its probably a good deal for both parties and its something now where I want to concentrate on my football.
“We need to keep improving as a team, not just me as an individual. I feel, if we improve as a team, Ill be a success too.”
United have fallen five points behind the top four, so they will be desperate to get back to winning ways after the international break when they face fierce rivals Liverpool at Old Trafford on 20 October.
