Andres Iniesta believes Barcelona must embrace change heading into next season as they target Champions League "revenge".
A 7-0 aggregate thumping at the hands of Bayern Munich saw Barca bow out of Europe in spectacular fashion last month, although the La Liga title helped ease those woes.
Iniesta believes the permanent return of coach Tito Vilanova and the arrival of Brazilian forward Neymar will allow Barca to close in on the treble next season.
"There will be changes, because it is the evolution that has to happen every year in order for the club to continue competing at the highest level," he said in an interview on Cuatro.
"Next year, we will not reach the semi-finals of the Champions League with practically no competition. We will try to take our revenge in this competition."
Iniesta played 30 minutes in Spain's 2-1 friendly win over Haiti on Saturday and insists he left Barcelona in good spirits.
"I feel content at having finished a season and I have the feeling things have gone well, more or less," he contined. "You can't analyse it by the goals you've scored or the assists you've been able to create, because there are many more crucial things in the game that mean more than how many goals or passes.
"My goal is simply to finish the year and think I have done better than in the last one."
