AC Milan vice-president Adriano Galliani conceded they focused too much on their Club World Championship campaign after last night's Champions League exit at the hands of Arsenal.
"We knew it would cost a great deal in terms of physical and psychological energy, but it remains an historic season and there is no need to change."
The Rossoneri were the reigning Champions League winners and also took the Club World Cup and European Super Cup, but exited the competition 2-0 to Arsenal.
"I believe Arsenal played better than we did over the 180 minutes and so deserved to go through. No club has won the Champions League twice in a row since us in 1990-91, so we couldn't break that taboo," said Galliani.
"We did really well in the opening 15-20 minutes and there was a period of Arsenal pressure, but we conceded a goal right when Arsenal seemed to be on a downward spiral.
"Unfortunately it was decided in midfield and we had some players returning from injury, others out completely like Clarence Seedorf, so it was very bad timing.
"This is football and we must focus on our next challenge. Let's not forget we are the club with the most trophies in the world and in 2007 we won three prestigious cups."
