Lionel Messi returned to Barcelona training for the first time since his fallout with the club over his future on Monday. The 33-year-old trained alone at the Catalan clubs Joan Gamper Ciutat Esportiva complex, the first time he has done so since the arrival of new manager Ronald Koeman. Barcelona begin their La Liga campaign against Villarreal on 27th September. Messi, a six-time Ballon d'Or winner, has been with Barcelona since the age of 13 and is the club's all-time record goalscorer.
