The veteran striker says he expects to fulfil his current deal with the Blaugrana.
He told Sport: "Until 2021, with option to 2022. I feel very happy, very happy here. I feel that in the club they value me a lot, although sometimes they want to misunderstand things.
"They value the effort I make at all times, which I always give my all to the club. I am in the best team in the world, in which I always wanted to play.
"The family is very happy and I hope to spend more time at Barça."
