Arsenal hero Martin Keown took aim at Mohamed Elneny after their defeat to Europa League opponents Ostersunds.

Arsenal were beaten 2-1 on the night but still advance courtesy of a 4-2 aggregate win.

Keown was extremely frustrated with the role Elneny played in Ken Sema's goal, as the Egyptian surged forward and was caught out of position.

“Within the build-up for that, Elneny, I'm not sure he knows his role and responsibilities in midfield," he told BT Sport.

“I watched Rakitic and saw Busquets play the other evening and they sat in midfield.

“Elneny is running ahead of (Jack) Wilshere, Wilshere's coming back and is the deep-lying man.

“Know your responsibility in the team, the protection is not there.

“You've got to protect these two young central defenders, especially when the two full-backs push forward like they do."
