Home form crucial to wenger
Arsene Wenger believes his side's form at the Emirates Stadium will dictate whether they can mount a sustained title challenge.
The Gunners head into the showdown with leaders Chelsea unbeaten so far this season - kicking off their European campaign with victory in Montpellier before battling to a draw at Manchester City, then sweeping past Southampton 6-1 and thumping Coventry by the same scoreline to reach the last 16 of the Capital One Cup.
After a goalless draw on the opening day with Sunderland, Wenger has challenged his side to make Emirates Stadium a fortress as they look to last the distance this time around.
"If we do well at home against the strong teams, it will of course have a big impact on our chances in the league," said Wenger.
"We have played one [big team] where we got some belief, against Manchester City away.
"Saturday it is another one, but it is a different one because we are at home."
