Unai Emery has been sacked as Arsenal manager after 18 months in charge.
The Spaniard, who previously led Paris St-Germain to the French league title and won three Europa Leagues with Sevilla, was appointed Gunners boss in May 2018, succeeding Arsene Wenger.
He is to be replaced on a temporary basis by assistant and former Arsenal midfielder Freddie Ljungberg.
Arsenal said the decision had been “taken due to results and performances not being at the level required”.
“The decision has been taken due to results and performances not being at the level required. We have asked Freddie Ljungberg to take responsibility for the first team as interim head coach. We have full confidence in Freddie to take us forward. The search for a new head coach is underway,” the club stated.
