The tall Swede said he was misquoted in Italy over an interview he gave in his homeland before a recent Euro 2012 qualifier and that he was not down in the dumps.
"I'm not sad, I'll have to teach people Swedish because they didn't understand what I said in that interview," he said after scoring in the 2-0 Champions League win over BATE Borisov.
"I'm fine and I think I showed that on the pitch."
"I think we played really well and created lots of chances," said Ibrahimovic, who has scored in each of their last two European games after missing the opener against former club Barcelona through injury.
"We are aiming to win every competition we are involved in. We cannot afford to relax, we have to keep working hard to keep improving and I hope we can better than last year."
Nigerian full-back Taye Taiwo, whose rocketing left-foot shot resembles that of former Brazil international Roberto Carlos, added a new dimension to Milan in Wednesday's game.
"It was good to give Taiwo a chance to show what a good player he is. He's getting a lot better in training," said coach Massimiliano Allegri.
"I'm getting more and more faith in my abilities in training and during the games and I think you can see that when I play," he said.
"The league is very difficult. I've been watching lots of DVDs to learn what I can. In the Champions League the play is different.
"I know it a bit better than I know Serie A because I have some experience in playing there."
