The Spaniard's future at Barcelona has been subject to speculation this summer.Casado enjoyed a tremendous start to the 2024-25 campaign, but fell behind in the pecking order after Frenkie de Jong's return to full fitness. The 21-year-old finished the campaign with one goal and six assists from 36 games across competitions.Casado's situation with the Catalans is unlikely to improve in the upcoming campaign. The LaLiga champions are spoilt for choice in midfield, with the likes of De Jong, Gavi, Pedri and Dani Olmo already on their roster.Talented young midfielder Marc Bernal has recovered from an unfortunate ACL injury picked up last season and is expected to be in the mix as well. As such, Barcelona could be open to Casado's exit this year.Atletico Madrid are keeping a close eye on the situation and are now plotting to prise him away. Diego Simeone is looking to add more quality to his midfield and has set his sights on the youngster. Casado is under contract at Camp Nou until 2028.Eric Garcia agrees renewalEric GarciaEric Garcia has agreed to sign a new deal with Barcelona, according to SPORT.

Eric Garcia was also linked with an exit from Camp Nou in January, but Flick refused to let him go.Barcelona were locked in talks with the player's camp regarding a new deal in recent times and have now reached a breakthrough. The Spaniard has apparently agreed to extend his stay until 2030, although an official confirmation is awaited.Denzel Dumfries wanted to join Barcelona this summerDenzel DumfriesDenzel Dumfries was eager to move to Camp Nou this summer, according to La Gazzetta dello Sport via SPORT.

However, the LaLiga giants failed to complete the transfer due to their financial constraints.
