Real Madrid have sacked Julen Lopetegui as manager after four and a half months in charge at the Bernabeu.
The Spaniard succeeded Zinedine Zidane in June but the crushing 5-1 loss to Barcelona in El Clasico on Sunday was their fifth loss in six games.
Real, Champions League winners for the past three years, are ninth in La Liga after their worst start since 2001-02.
The 52-year-old will be “provisionally replaced” by ex-player Santiago Solari, coach of B team Castilla.
Lopetegui took a training session on Monday but his fate was confirmed following a board meeting.
A club statement said “there is a great disproportion between the quality of the staff of Real Madrid” and “the results obtained to date”.
Eight of the current Real squad are on the 30-man shortlist for the 2018 Ballon d’Or.
Solari has a favourable run of fixtures for the start of his tenure, beginning with a Spanish Cup match against Segunda Division B Group 4 side Melilla on Wednesday.
Real then play Valladolid – sixth in La Liga – on Saturday, Group G’s bottom side Viktoria Plzen in the Champions League on 7 November, and the mid-table Celta Vigo the following Sunday.
It is the second time Lopetegui has been sacked this year having been dismissed by Spain two days before the World Cup.
