Roberto says he's happy at Barca, but plans to spend the latter stages of his career in the US.
He said, "I would like to go to the United States in the last years of my career. Barça is the club of my life and competing in Europe I would like to always be here, but I would like an experience in the MLS. I did not imagine that at 28 years old I would be in Barcelona being one of the captains."
On teammate Lionel Messi, Roberto continued: "I thought the same as any culé, that it could not be true that Leo did not continue with us. I cannot imagine a Barça without Messi and I crossed my fingers so that he would stay.
"Since I was in the first team I have always seen him with the same desire and ambition. Now it will be no less."
