The Chilean attacker says the Blaugrana will be suitably prepared for what awaits them at San Siro on Tuesday following their humbling defeat last season

Alexis Sanchez says Barcelona will be a different team to the one that AC Milan tactically outclassed in San Siro last season when the sides meet in the Champions League on Tuesday.

Barca were humbled 2-0 in Milan in the first leg of the last 16 encounter back in February as Sulley Muntari and Kevin-Prince Boateng goals ensured a comfortable victory.

The return leg saw the Catalans overturn Milan's aggregate lead with an emphatic 4-0 win at Camp Nou, but the memories of the San Siro defeat will spur the Blaugrana on to make sure there is not a repeat result in the Group H match, according to Alexis.

"We learned from last year's experience [2-0 loss against AC Milan in the San Siro]," he told reporters ahead of the game.

"Milan have always shown great heart, it is important to play 90 minutes with great concentration. I always give my 100 per cent."

The Chile international has been criticised from some quarters as they believe he has not reached his full potential since his €26 million move from Udinese.

However, the 24-year-old, who has scored 30 goals in 97 appearances for Barcelona, says detractors spur him on to do even better.

He added: "In Barca there are so many good players. I am ready to play but I do not feel like a starter.

"The criticism gave me more strength. Playing with Neymar gives me happiness and confidence."
