Mikel Arteta defended his decision to play Bukayo Saka as the Arsenal winger limped out of their Champions League defeat to Lens. The Gunners had taken the lead through Gabriel Jesus but Adrien Thomasson levelled following a David Raya error before Saka hobbled out of the game. Lens would go on to win 2-1 courtesy of a second-half strike from Elye Wahi but it was the injury to Saka that will have concerned Arteta more. The Arsenal boss described Saka’s injury as a “knock” at full-time, adding the club are now waiting to see the extent of the issue.
