Alex Calatrava, a 25-year-old attacking midfielder from Castellón, has five goals and four assists in 21 LaLiga Hypermotion matches. According to Mundo Deportivo, Espanyol has recently inquired about the situation of Calatrava. Calatrava renewed his contract in August until 2029. The interest is informal and adds to the interest from last summer, when Manolo and his assistant, Gerard Garrido, requested his signing. Manolo González stated that Calatrava is the attacking midfielder they have been asking the club for for a long time and that they are still asking for that type of player. The increase in the release clause following the contract extension is a factor against Espanyol, while the player's willingness is a factor in their favor. If there is an agreement between the clubs, Calatrava will agree, although this is expected to be more likely next summer because Castellón is fighting for promotion and he is their undisputed leader.

Mundo Deportivo reports on Álex Calatrava's potential transfer to Espanyol, highlighting the player's preference due to proximity to his home. Espanyol is Álex Calatrava's preferred option due to proximity to his home, Parets del Vallès. Castellón would accept a transfer fee of around 3 million euros, despite his release clause being 5 million euros.

Espanyol is reportedly charmed by Álex Calatrava and is interested in signing him. The club is among several Spanish clubs showing interest in the player. Calatrava, a 24-year-old winger, has been a standout performer for Castellon this season, featuring in 32 matches and contributing six goals and eleven assists. Although his contract includes a release clause of five million euros valid until 2028, no decision regarding his future has been finalized. Espanyol, along with Real Mallorca, Alaves, and Villarreal, is competing to secure his signature, but these clubs have not yet committed to meeting the release clause. Additionally, Calatrava is attracting attention from clubs in the MLS, Germany, and Italy, with Como and Ajax among the interested parties.
