The Argentine whiz is returning to Spain after a short break following the Copa America and is aware of speculation linking him with Inter Milan.
"If it was up to me, I'd never leave Barcelona," Messi told DiarioSport.
"The treatment I have received from the people and the club has been spectacular. I always say this and perhaps people believe it's just a line I trot out. But it's the truth!
"I am happy at Barcelona, I have everything there and do not want to play for another team."
