I came here when I was 18 years old with my brother in Castilla. I left home to be at Real Madrid. I’ve lived & drank Madrid.”I have complete loyalty & I am very clear on what loyalty is. I hope Spain have a magnificent World Cup.”Lopetegui knows Madrid well, having played for Castilla for several seasons as a player and also coaching the club’s B team at the start of his career on the bench. He boasts European Championship medals at both Under-19 and 21 levels from his time directing Spain’s youth divisions, and was most recently in charge of Porto prior to taking the national team job in 2016.
