Barcelona, though, are adamant that they will only let the 22-year-old leave for above €90m. Previously reports have suggested that Lopez wants to stay at Camp Nou, but speculation is ripe regarding his next move. Hansi Flick views the Spaniard as a key part of his plans, and wants him to stay. Marc Casado makes future decisionMarc CasadoMarc Casado will not leave Barcelona this summer, according to journalist Jordi Cardero. The Spaniard is wanted by multiple clubs at the moment, with the player no longer a first team regular under Hansi Flick. Last season, the 21-year-old lost his place to Frenkie de Jong in the second half of the campaign. With Marc Bernal close to a return from the ACL injury, and Gavi and Pedri also in the mix, Casado could find game time very hard to come by.
