Bacary Sagna has admitted that Arsenal need to beat Manchester United on Saturday.
The Gunners have produced several stunning performances this season but they have failed to find any consistency and have also lost three times in the Premier League.
The 2-1 defeat to Stoke at the weekend left Arsenal six points adrift of leaders Chelsea and Liverpool, and Sagna realises they cannot afford to drop points against United.
"We know this game is very important and we have to win it," the Frenchman told Arsenal TV Online.
"So it will be a very good game for us. We will want to show Arsenal are still here.
"We want to take three points."
Sagna's fellow defender Gael Clichy, meanwhile, has admitted that Arsenal lacked focus against Stoke.
The Gunners failed to deal with Rory Delap's long throw-ins at the Britannia Stadium and Clichy feels a better option would have been to concede corners.
He said: "You realise that maybe it is better to put the ball out for the corner rather than the throw-in because they are so good and it's their main quality so it is really bad, it's disappointing.
"We didn't play well but we controlled the game and they scored on two throw-ins so maybe we weren't focused enough on the throw-in.
"The rest we did quite well: we tried to avoid the corners, the set-pieces, maybe we should have tried to avoid the throw-in as well but the focus wasn't there.
"We have to look forward, what is behind is behind.
"But it was a big disappointment again."
