Now fully fit, Bailly has recently signed a new deal with United.
He told MUTV: "Through all the tough times I've had, the club has always shown a lot of faith in me.
“And, as part of that show of confidence, they have given me this contract extension.
“So I need to be thankful for the confidence that they have shown in me, thankful and ready to give my best when I return to the team, to show them that I am completely behind the team, and, hopefully, to go on to lift some silverware in the future.
“There are still a lot of matches to be played. We're still in all the different cups - the FA Cup, League Cup and the Europa League, as well as continuing to work in the Premier League. We're going to keep on it in training and stay united as a team, right through to the end of the season."
Bailly insists he had no problem sitting out Sunday's FA Cup win at Tranmere Rovers.
“I had some difficult times last year but, once those times have passed, they are the past, and it's time to make the most of these opportunities now presenting themselves.
“I'm fit and well, I'm back training with the team, building confidence for my return. This is going to be a very important year.
“Given those conditions [at Tranmere], it wouldn't have been the right pitch for a player returning from a long-term injury to start his returning match on such a surface.
“But I was happy to be with the team, to see them win the game, and that's my focus, to prepare for the day when I'm back playing with them."
