Arsenal manager Arsene Wenger is aware of how quickly his side's fortunes could change.
After a topsy-turvy season, the Gunners finally seem to be on track again, heading into Wednesday night's Champions League last-16 clash with AC Milan having reclaimed their place in the Barclays Premier League's top four.
But, with so much still to play for and having been burned in the past, Wenger is aware of how cautious his side need to be.
"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 a fire with strong wind so you have to be a bit cautious because it can quickly come back. The wind can blow it quickly 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."
