Arsenal lose trio for Olympiakos clash

Arsenal will be without defender Laurent Koscielny and forwards Theo Walcott and Gervinho for Wednesday’s Champions league match against Olympiakos, manager Arsene Wenger said.
Koscielny has an ankle injury, Walcott a knee problem and Gervinho a mild muscle strain but all three could be fit for Sunday’s Premier League match against Tottenham Hotspur.
Arsenal drew their opening Champions League Group F match against Borussia Dortmund 1-1 and lie 13th in the Premier League after a disappointing start to the season.
