Ibrahimovic who is out of his contract in the summer, is yet to announce his plans for next year.
Raiola speaking with Talksport, said; "Anything can happen, let's enjoy the moment and we will see what happens next year."
"We ae now concentrating on the next cup. This was a very important cup, very emotional for him, for me, for Mourinho. Let's give the fans some more cups."
Manchester united boss, Jose Mourinho also joked that United fans ought to camp outside Ibrahimovic's house and persuade him to sign a deal.
In Mourinho's words;
"I never beg a player to play for me, but we all want and believe he will stay one more season.
"I never beg for a player to sign a contract. But, if indeed, the fans can go to the door of his house and stay there all night."
