Barcelona coach Tito Vilanova admits they've learned a lot from this season's campaign.
He admits there is plenty to improve on following a testing season on and off the pitch with illnesses, injuries and some surprise results, including their 7-0 aggregate Champions League mauling by Bayern Munich.
He said: "We always must try to improve. This year has taught us all a lot because of everything we experienced.
"It has been a difficult year because of the injuries and because the head coach wasn't here for two months. Next season things will be different, although that's normal because it's my first year."
