Gunners manager Arsene Wenger revealed his KO headache ahead of huge London derby
ARSENAL could be without FIVE key players for tomorrow's derby clash against Chelsea.
Defender Sead Kolasinac joins Nacho Monreal and Olivier Giroud on the crock list after being ruled out for two weeks.
The burly Bosnian limped off the pitch and was replaced by Ainsley Maitland-Niles after just 37 minutes during the 1-1 New Year's Eve draw at the Hawthorns.
And Gunners boss Arsene Wenger is sweating on the fitness of duo Mesut Ozil and Laurent Koscielny.
Ozil missed the Baggies game with a knee injury and Koscielny was forced off crocked in the 72nd minute after asking to be substituted.
Speaking ahead of tomorrow's Premier League clash, Wenger said: "We lost Kolasinac, Koscielny in the game [at West Brom].
"The two who have a little chance . . . Ozil might have a test this morning. Koscielny is 30-70 available."
Chelsea are likely to recall Eden Hazard to the starting XI after he was dropped to the bench for the 5-0 thrashing of Stoke.

Tomorrow's clash is a perfect chance for Arsenal to get one over on a top-four rival.
