Arsenal had enough worries over defensive injuries before Wednesday’s trip to Turkey where Laurent Koscielny suffered a horrific injury.

The Gunners were impressive in their 3-0 victory over Fenerbahce but they were sweating over the health of their French centre-back after he went down with his face bleeding.

Just over half an hour had gone when Koscielny went to header a bouncing ball but was booted full in the face by Fener striker Pierre Webo.

The replays showed it to be an almighty blow to the Frenchman’s head and medics rushed on to the pitch to stop the bleeding, before rushing him off to hospital.

Arsenal manager Arsene Wenger said the club were waiting for news on the full extent of the injury, but confirmed it was serious.

“We have to check that there's no bone broken. He opened the skull but it's very deep, it's very, very deep,” he told reporters after the game.

Meanwhile, Arsenal physio Colin Lewin described it as one of the worst cuts he has seen during his time in the game.

Fears of something more serious were allayed later in the evening when Koscielny’s teammate Olivier Giroud posted a picture of the defender on Instagram, reassuring fans he would be fine.

The 27-year-old will miss Saturday’s Premier League encounter with Fulham in any case, as he will be serving a one-match ban after getting sent off in the opening day loss to Aston Villa.
