Real Madrid has sacked manager Julen Lopetegui on Monday after just 14 games in charge following the 5-1 defeat to Barcelona at the Nou Camp.
The defeat leaves Real Madrid ninth in La Liga, seven points behind leaders Barcelona.
Announcing the decision on Monday night, Real Madrid said: “This decision aims to change the dynamics of the first team when all the objectives of this season are still achievable.
“The Board of Directors understands that there is a great disproportion between the quality of the staff of Real Madrid and the results obtained to date.
“The club thanks Julen Lopetegui and all his technical team for their effort and work and wishes them the best in their professional career.”
Lopetegui, who was named as Real manager days before he was preparing to lead Spain into this summer’s World Cup, won four of his 10 league games in charge.
Their last league win was a 1-0 win over Espanyol on September 22 and has been followed by four defeats and a draw.
Lopetegui, 52, has now lost two jobs in the space of less than five months.
He was sacked from his job as the head coach of the Spanish national team the day before the World Cup commenced in June, due to having planned his move to Real without informing the Spanish Football Federation.
Santiago Solari will step up from Real Madrid’s B-team ‘Castilla’ to replace Lopetegui.
Solari, aged 42, is a former Argentina midfielder who played for Real Madrid in the early 2000s and helped the team win the 2002 Champions League. He also played for Atletico Madrid and Inter Milan.
He had been coaching Real Madrid B since 2016, taking over not long after Zidane left to coach the main squad.
