"I'm very happy," Messi told Perform, which owns Goal. "I have plenty of desire to come back and play football after such a long time out. I'm lucky because step by step I'm starting to feel better, with a lot of vision to have a great year - not just with Barcelona but also with Argentina.
"Every year I start with the same mentality to have a good year. To keep growing and improving, to always be at the same level. Before the World Cup we have a lot of important things with Barcelona. We have the Champions League, La Liga and the Copa del Rey and that is not the only motivation for me, but [also] for all of us to keep growing."
