Conor Gallagher has officially signed with Atlético Madrid after departing Chelsea, ending an 18-year association with the club. The transfer, which was complicated and delayed, concluded with a fee of approximately £34 million, allowing Gallagher to finally join his new teammates. He expressed excitement about the move, not only for playing at a prestigious club but also for the cultural experience in Spain. Gallagher was welcomed at a presentation event at the Estadio Metropolitano, where he was introduced alongside other new signings. He has already begun training with his new team, aided by former Chelsea teammate César Azpilicueta, who is helping him adapt to the language and environment. Gallagher's first match with Atlético Madrid is anticipated against Girona on August 25.
