Barcelona winger Alexis Sanchez says they won't repeat the mistakes of last season's Champions League campaign.
Barca face AC Milan tonight, having lost to the Rossoneri last term.
"We learned from last year's experience [2-0 loss against AC Milan in the San Siro]," said Alexis.
"Milan has always shown great heart, it is important to play 90 minutes with great concentration. I always give my 100 per cent.
"In Barça there are so many good players, I am ready to play but I do not feel a starter. The criticisms gave me more strength. Playing with Neymar gives me happiness and confidence."
