Ibrahimovic inspired Sweden to a 4-2 win in the inaugural match at the Friends Arena after England had led 2-1 at half-time through goals from Danny Welbeck and debutant Steven Caulker.
Gerrard said: "I have mixed emotions. Obviously I am very proud for myself, getting to 100 caps and really pleased with the lads for large parts of the game.
"I thought we controlled the game and did not look like losing it but sometimes you have to hold your hands up to an individual special performance.
"This was a world-class performance from a world-class player in Ibrahimovic. It (the fourth goal) is the best goal I have seen live.
"I think the best goal I have seen before that is Wayne Rooney's (against Manchester City).
"Everyone knows how special that was but this one tonight - an overhead kick from 25 yards when the ball is six feet in the air - only certain players can do that.
"He is a special player."
Gerrard added: "I congratulated him after that. He said some nice things about me before the game which was really nice.
"If I could return the compliment I would say that was one of the best individual performances I have seen.
"He is not everyone's Cup of tea but he is certainly mine."
