Arsenal lacked sharpness - Arsene Wenger

Arsene Wenger admits Arsenal found it difficult to raise themselves after the "high" of the weekend's swashbuckling victory over Chelsea, but is satisfied after the 1-1 Champions League draw with Marseille.

The Frenchman was particularly pleased with his defence, after the clean sheet at the Emirates against the lively visitors maintains his side's place at the top of Group F.
