Maguire slipped down the pecking order at United last season, with Raphael Varane, Lisandro Martinez and Victor Lindelof the preferred options in central defence, and was linked with a move to West Ham United in the transfer window.
However, the defender opted to stay and has taken advantage of injuries to Varane and Martinez to re-establish himself in United's first team, starting their last eight games in all competitions.
Asked if his run served as vindication for staying at Old Trafford, Maguire told reporters: "Of course".
"Rapha (Varane) and Licha (Lisandro Martinez) were playing brilliantly and kept numerous clean sheets. I had to bide my time and be patient," the England defender said after United's 1-0 win over Luton Town on Saturday.
"I had two or three opportunities last season to get a run of games but I broke down with illness, I broke down with injuries twice, so I never got the rhythm and never got the run of games that I could prove myself to the manager.
"I have got that now, I am really enjoying my football and I really enjoy playing for this club."
United, who are sixth in the Premier League, next travel to 14th-placed Everton on November 26.
