Lionel Messi returned to train with Barcelona for the first time since his massive fallout with the Catalan club. The 33-year-old trained alone at the complex in Barcelona since the arrival of new manager Ronald Koeman. After a bitter battle with Barcelona around his transfer fee and release clause, Messi said that he will only stay in Spain to avoid facing his club in the court. As the new season of La Liga starts this month, Barcelona who finished 2nd last season will play Villarreal on 27th September. Messi has been with Barcelona since the age of 13 and is the club's all-time record goalscorer.
