Kieran Gibbs and Marouane Chamakh have been ruled out of Arsenal's game against West Bromwich Albion on Saturday due to injury.

Manager Arsene Wenger revealed that Chamakh has a knee problem, while Gibbs is struggling with a strain of his stomach muscles.

"[Chamakh] has a little inflammation in his knee," said Wenger. "There is a little effusion and he will not be available for Saturday. I think he will miss the international games as well. Hopefully he should be ready again after the international break.

"[Gibbs] is not available for Saturday as well. He is progressing normally, a bit slower than expected but there's a chance he might be available after the international break."

Meanwhile, Thomas Vermaelen is expected to start at the Emirates Stadium after he played a full 90 minutes against Marseille on Tuesday.
