Lionel Messi, the Argentine professional footballer, has won numerous trophies throughout his career. As of my last update in January 2022, Messi has won over 40 major trophies at the club level with Barcelona, including numerous La Liga titles, Copa del Rey titles, UEFA Champions League titles, and FIFA Club World Cup titles. He has also won several individual awards, including multiple Ballon d'Or titles.
Since my training data only goes up to January 2022, for the most current count of Messi's trophies, you may need to verify the information through recent sources.
