Ibrahimovic has entered the final year of his contract with Paris Saint-Germain and has said his next club will be a surprise.
The outspoken Swede who scored in the 2-0 win over United in the ICC has been linked with a number of clubs, including one in the MLS.
But the forward is not keen on releasing which team that is yet and insists it will be a big surprise.
“Where I go next, it will be a surprise, a very big surprise,” the PSG striker told reporters with a smile after the United victory.
“I’m very happy at PSG. You don’t see that on the field? I have another year on my contract with PSG and I am very happy.
“Things are getting better. We are a strong team, we can do much more than we have been doing so at the moment but I am very happy.”
Victory over United – coupled with earlier wins over Benfica and Fiorentina – saw PSG lift the International Champions Cup, but Ibrahimovic has his sights set on grander prizes- starting with the Trophee des Champions against Lyon in Montreal on Saturday.
“The (trophy) we won today is only for the preparation. This is nothing official,” the striker insisted.
“This is only to prepare our condition mentally and physically for the season.
“We have been here 15 days, played all the friendly games and now we go over to the official game against Lyon, that is the Super Cup so if we can win that one we will win our first trophy for the year, so that would be very good.”
