A coach since 1997, Marcelino has had success at practically every club he has taken charge of, leading three sides to promotion to La Liga, two into the Europa League and one into the Champions League.
He also won the 2019 Copa del Rey with Valencia, beating Barcelona in the final, after securing back-to-back top-four finishes with the team - but was sacked early the following season after falling out with owner Peter Lim.
Non-sporting reasons also led to him leaving Villarreal after reaching the 2016 Europa League semi-finals, with Spanish media reports saying he had been dismissed following a breakdown in his relationship with players.
Known for his attention to detail and a particular focus on players’ diets and weight, Marcelino has been described by former players as both a pain in the neck and the best coach they have ever had.
“We are ambitious about repaying the confidence that has been shown in us to coach this historic club,” Marcelino told the club’s website after being appointed.
