Barcelona ace Lionel Messi insists the critics cant unsettled him.

Messi's form was questioned last month when he went for a short spell without scoring.

"I do not care if someone wants to hurt me. They were only three games. The guys supported me, worried that criticism could affect me. But that did not happen at any time," said Messi.

He added: "I've won everything with Barca - and I want to win it all again. I want to keep improving."
