Arsenal have sacked manager Unai Emery following a run of seven games without a victory and Freddie Ljungberg will take over as interim coach, the Premier League club announced on Friday.

Spaniard Emery leaves the side after 18 months in charge, with the club eighth in the Premier League standings after four wins in 13 matches.

"The decision has been taken due to results and performances not being at the level required," the club said in a statement.

"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."

Emery is sacked after seven straight losses of Arsenal, currently ranking eighth in the English Premier League. 

Thursday saw Emery's last game as head coach, when Arsenal lost 1-2 to Frankfurt in the Europa League. Arsenal led by one goal by Pierre-Emerick Aubameyang right on half-time, but Frankfurt turned the game around with two goals from Daichi Kamada in the second half.
