Robin van Persie feels Arsenal are about to embark on a crucial phase of the season.

The Gunners extended their unbeaten run to 12 matches with a resounding 4-1 demolition of AZ Alkmaar at the Emirates Stadium on Wednesday night to all but secure a place in the last 16 of the Champions League.

With leaders Chelsea and Manchester United - on whom Arsenal have a match in hand - clashing at Stamford Bridge on Sunday, the trip to Wolves on Saturday evening represents a real opportunity for Arsene Wenger's young side to lay down a marker ahead of the international break.

"It is a very crucial time for us now," said the Holland striker. Against Wolves, it is a must-win game for us, given that Chelsea and Man United are playing each other.

"After the break we have Sunderland away and then Chelsea, so it will be a tough month, but I am looking forward to it."

"We are looking sharp at the moment. Everyone wants to play together and as long as we are enjoying ourselves together we can continue like this."
