Arsène Wenger believes keeping the “fire” of crisis away from the Club will be central to their hopes of success this season.

Arsenal moved into fourth spot in the Premier League on Saturday after their late win at Sunderland, while Chelsea and Liverpool both lost.

Wenger is confident his team have the quality and desire to secure a top-four spot, but insists their next run of games could define the rest of their season.

"You could say that the crisis at the moment in England is a bit like fire. It moves very quickly from one club to another,” he said.

"It's like a fire with strong wind so you have to be a bit cautious because it can quickly come back. The wind can blow it back!

"This is the important time for us. Before the week started, I said that this week would be vital for us. It's down to us to do well and hopefully we will do it.”

Wenger believes that keeping as many of his squad fit for the remainder of the campaign could prove crucial.

"We play in many competitions now and we can't lose a player like Per Mertesacker in every competition. What is important for us now instead of losing a player is getting players back,” he said.

"If we can get Diaby back, Wilshere back and not lose any players in the defensive sector then we have a chance but we'll see. This week is vital for us.”
