Hit man Ibrahimovic is recovering from an knee injury suffer in the Europa League quarter-final against Anderlecht in April.
The Swedish striker is out of contract this summer after netting 28 times for United in his debut campaign at Old Trafford.
Reports from Old Trafford have hinted Ibrahimovic will not be taking up the 12-month extension on the contract but Pogba insists whether he is playing for Jose Mourinho’s side or not he will bounce back.
“He is a player who helped us a lot from an athletic point of view as well as from the mental side on and off the pitch,” Pogba said on Sky Sports.
“He’s a wonderful person, incredibly funny, I only spend great moments with him.
“On the pitch he is a winner, he added this mentality to our team.
“He scored a lot of goals this season, nobody would have thought that given his age.
“He was unlucky and suffered a bad injury but he won three trophies with us. He will always be Zlatan.
“He’s a guy who is always joking, if he was here right now he would make fun of your shoes. ‘Wow, why do you wear nice shoes?’.
“He would start to make jokes about your clothes for example, he’s like this but he doesn’t mean it in a negative way.”
