Ibrahimovic is yet to formally extend his initial 12 month United contract and is not expected to come to a decision until the end of the season. He has been strongly linked with both LA Galaxy and Los Angeles FC in Major League Soccer and his future remains up in the air.
Conflicting stories on whether he will stay or go seem to emerge every few days and some people have interpreted the hardly shocking admission of a 35-year-old not having long left in his career as a hint that he could be ready to walk away from the top level.
"I will not lie, the season has been great. But I'm always comparing my seasons to the seasons I've been doing. My last season was amazing," Ibrahimovic told BT Sport on Thursday night after United got the better of Anderlecht in the Europa League quarter finals.
"I'm happy I chose this club because I think this club is the biggest in Manchester, in England and one of the biggest in the world. I have nothing else to prove, everything has been said. I want to collect as many trophies as possible and enjoy," he added.
"I don't know how long I have left. Rashford, Lingard have long careers in front of them. I was there 15 years ago, I don't know how long I have left."
United fans may not see Ibrahimovic again this season after an awkward fall in the Anderlecht clash left him with a suspected knee injury. Jose Mourinho's early verdict was less than optimistic and it is now increasingly expected he won't return before the end of the campaign.
