Ibrahimovic is expected to lead the line again against Everton on Tuesday night after serving a three-match domestic ban.
United have picked up just four points from a possible nine in his absence – most recently held to a frustrating draw at home to West Brom – and lie five behind rivals Manchester City, albeit with a game in hand.
But the man who has netted 15 times in the top flight this season has declared himself ready to bring back “positive vibes” as the quest for Champions League qualification gathers pace.
“I feel good,” he told MUTV. “I missed Old Trafford and the games with my team, but finally I am back and hopefully I come back with positive vibes.
“One game can change a lot – suddenly you can be third, fourth, fifth, sixth.
“First is too far away, second probably also, but otherwise it’s very tight and if you succeed in winning two or three games in a row then you’re in the Champions League spots.
“I think we will make it and we will be there. We have gained the points we need to be in the Champions League, though we are on the limit now. A little bit more and we will reach the top four I believe.”
