Barcelona fans gathered outside the club's Camp Nou stadium after the bombshell news that star player Lionel Messi has requested a transfer. The club's fans, undeterred by the coronavirus pandemic, wore masks and voiced their anger with chants aimed at club president Josep Maria Bartomeu. It was reported on Tuesday evening <a href="https://www.thenational.ae/sport/football/lionel-messi-hands-in-barcelona-transfer-request-1.1068386">that Messi's lawyers had sent a fax</a> stating the Argentine's desire to end his contract by triggering a release clause. "I don't see him anywhere else. I can't believe it," said Ruben Tejero, 28, one of about 100 fans at the stadium calling for Bartomeu to resign. "I prefer to think it's an ultimatum given to management for Bartomeu to go," AFP reported him as saying. Barcelona have yet to respond publicly but are understood to believe Messi's release clause expired in June, and that he remains under contract until the end of the 2021 season. Messi endured a frustrating season as Barcelona were pipped to the La Liga title by rivals Real Madrid, and they suffered a humiliating 8-2 defeat to Bayern Munich in the Champions League semi-final - <a href="https://www.thenational.ae/sport/football/lionel-messi-s-heaviest-defeats-barcelona-s-8-2-loss-to-bayern-is-star-s-worst-by-some-way-1.1063827">the heaviest loss of Messi's career</a>. The 33-year-old made his Barcelona debut aged just 16 in 2003. Former teammate and Barcelona legend Carles Puyol gave his approval to Messi's decision on Twitter, saying: "Respect and admiration, Leo. All my support, friend." The tweet was responded to by Barcelona striker Luis Suarez, who just a day earlier was reported to have been told by new manager Ronald Koeman that his time at the Camp Nou was up.
