Gael Clichy has warned his Arsenal team-mates that a repeat of last weekend's performance versus West Brom would be football suicide against Chelsea.
The Gunners endured a hugely disappointing loss in their previous league outing as they lost 3-2 at home to newly-promoted West Brom.
Arsene Wenger's men must respond on Sunday when they travel to Premier League champions Chelsea at Stamford Bridge.
Clichy is wary of the stringent test ahead and has rallied his charges in a bid to iron out any complacency.
Of the Baggies defeat, he told The Sun: "That was a terrible game, very difficult to accept. For some reason the desire was not there and some players were tired... but at this level you can't hide behind tiredness.
"West Brom are a smaller side than Arsenal so we should have won, everybody knows that. But give them credit, they played very well. We have to get our heads down again and get back to work.
"When you play for Arsenal people expect better and I can assure you if we play at Chelsea the way we did against West Brom it will be very difficult indeed."
