#5 Julen Lopetegui
Julen Lopetegui became the manager of the Spanish national team on September 2016 after the retirement of Vincente Del Bosque from the role. He managed the side for two years, and his Spanish squad remained undefeated till his last day.
He won 9 of his World Cup qualifying games and drew 1, and his side was one of the favourites to go the distance in Russia. But on 12 June 2018, it was announced that Julen Lopetegui would take over as Real Madrid coach the following season, and the next day he was infamously let go by the Spanish Football Federation on the eve of the tournament, and replaced by Real legend Fernando Hierro.
His spell began with the departure of the club and arguably world's best player, Cristiano Ronaldo, to Juventus. He started his career with a loss against Atletico Madrid in the Super Cup.
Following the club's worst goal-scoring drought in its long history, and an emphatic defeat in the most recent El Clasico, he was let go by the management, and was replaced temporarily by Santiago Solari.
Stats: 14 games, 6 wins, 2 draws, and 6 losses (June 2018 - October 2018).
