Arsenal boss Arsene Wenger is concerned Sead Kolasinac won't be fit for their clash with Manchester City.
The defender produced a superb goalscoring performance for victory over Swansea City on Saturday. But he was forced off with a hip problem.
Wenger admitted that he could not be sure that Kolasinac would make next Sunday's trip to Manchester, where a defeat would leave Arsenal 12 points adrift of Pep Guardiola's league leaders.
“He had that already before but he came back today. It's a tight muscle in his hip. How long will he be out? I don't know; we hope to get him fit for next Sunday.
“He had that before and we managed to get him available.
“It came back a bit too much so I thought there's no need to take a gamble. He wanted to come off. I haven't spoken to him since."
