Ibrahimovic is confident United's squad is now healthy and strong enough to compete on all fronts this season, as they look to close the gap on Manchester City in the Premier League title race.
"I think we can chase City, why is it not a possibility?" said the Swede, according to Goal.
Ibrahimovic was handed a 13-minute cameo at Old Trafford for what was his first competitive appearance since picking up the serious injury in April.
Fellow former Manchester United striker Louis Saha, meanwhile, believes Ibrahimovic's return just seven months after a potentially career-ending knee injury will give United a fillip similar to when Paul Scholes reversed his decision to retire in January 2012. Against Newcastle it was like he hasn't been injured for a month, he brings such big quality, a different quality and I bring experience and mine. I try to help the guys much as possible and do what I can.
"I want to keep that to myself, though, because I don't need to tell the world - it's very sensitive".
"When you play for such a club, the expectation is incredible and you always have to win", You always have to play good and win, and, at the end of the season, lift trophies", Mata said. "I think this is hilarious".
"If I don't believe we can still win the league, I better stop. I don't know what the future brings but what happens, happens", Ibrahimovic explained, as reported by the Manchester Evening News.
"It's fantastic to be playing".
Asked about next term, the 36 year-old stated: "Right now, I'm just grateful to be able to play football again". I don't think Pogba makes a great deal of difference and we will see when they play the good teams. He has found it hard in a few games because the team didn't create a lot of chances, and the team didn't play as well as it could have, but I think he will be okay.
