Fletcher made an emotional playing return during victory at Aston Villa.
"It was nice for me to come back. Even at half-time I went to do a few strides and it was great, it means a lot when the fans support me like that, and it spurs me on to do well for them. To have the support of the fans after what I've been through is great," he told manutd.com.
"There have been so many people I could mention [who have supported me], but first and foremost are the people closest to home. Without them, I probably wouldn't have been able to come back.
"We have to go on a run, there's no doubt about it. Not just an unbeaten run, but we need to be winning games, and put ourselves in a position where we're still in contention by New Year. That's the goal for all the lads, and results like this away from home are a good starting point. But, we've got to go and do it again, we need to win several games in a row for people to start believing that we're back to what we are capable of.
"I'm still building up my fitness, but I don't want to take it easy. I've done enough of that, and I want to be involved, to get us back to where I know we should be. I think that's the biggest determination for me. It's difficult watching when the lads are winning, but a lot more difficult when they're not winning. I want to help as much as I can, I want to keep picking up minutes, even if it's with the reserves. Ultimately, the goal is to play in the first team, to be a part of the plans, and to bring success back to Manchester United."
