Marcos Fernandez transferred from Real Betis to Espanyol on 10 June on a free transfer. This move was part of the transfers completed by La Liga clubs on the final day of a mini transfer window introduced by FIFA to accommodate the inaugural summer Club World Cup. The window allowed clubs to register new players until 19:00 BST on 10 June, ahead of the Club World Cup starting on 15 June. Fernandez's free transfer to Espanyol was confirmed amidst a series of transfers occurring across Europe's top leagues as teams hurried to finalize deals before the window's brief closure.
