Barcelona Head Coach Ronald Koeman has been sacked after 14 months in charge at the Nou Camp.
Barca has picked up just 15 points from 10 games in La Liga and has already lost twice in the group stage of this season’s Champions League.
They are ninth in the table, six points adrift of the joint leaders after losing at Rayo Vallecano on Wednesday.
The loss was Barca’s third in their last four games and it followed defeat in Sunday’s Clasico to Real Madrid.
In a statement, the Spanish club said: “The president of the club, Joan Laporta, informed him [Koeman] of the decision after the defeat against Rayo Vallecano.
“Ronald Koeman will say goodbye to the squad on Thursday.”
The former Netherlands, Everton and Southampton boss, 58, could only guide the five-time European champions to third place in the league last season.
Speaking after Wednesday’s defeat, Koeman said: “It [Barcelona’s league position] says we’re not well.
“The team has lost balance in the squad, lost very effective players, which shows. In recent years other clubs have strengthened every season and we haven’t, which also shows.”
Club legend Xavi, the former Barca midfielder who is now manager of Qatari side Al Sadd, is one of the favourites to replace Koeman.
