Zlatan Ibrahimovic has admitted that he gave so much to Milan at the start of the season that he eventually ran out of juice.
Ibra made a sensational impact with the Rossoneri following his move from Barcelona, but he struggled in the last few months of the campaign.
Speaking to La Gazzetta dello Sport, he said: "I picked up two avoidable suspensions towards the end of the season, but my first six or seven months at Milan…
"I don't think that I have ever started a season so well in any other side. But perhaps I burned myself out, I ran out of petrol, mentally and physically.
"But we are Milan, we are a great side, and there were other players who did their job well while I was tired."
Ibrahimovic, who was a regular in the attacking plans of Massimiliano Allegri, was asked whether he'd be allowed to catch his breath next term.
"I don't know, Allegri will decide that with the club," he responded. "I'm paid to play football and I just have to do what they order."
Milan won the Scudetto with the help of Ibra, but the former Juventus and Inter ace insists that is only the first piece of the jigsaw.
"We have a great project that we are working on and I'll certainly be here," continued the striker.
"We won the Scudetto which was an important step in the right direction.
"I'm a positive guy and I believe in the club's plans. I just hope we can get to the very end as has been promised."
Ibra scored 14 Serie A goals for Milan, the same number as teammates Alexandre Pato and Robinho.
