The Barca striker is a target for Liverpool in January with talk of a £40 million looming.
But he insists: "I feel important, and even more so when the manager speaks well of me.
"I've always had the affection of team-mates and especially the public. I noticed it since the day I arrived. So it's not vital that I score.
"I don't give any importance to what is said outside the club. I don't have to be worried about all of this, it's all the same to me. I work so that the manager, my colleagues, the fans and my family are happy, and that's the case."
