Arsenal manager Arsene Wenger believes his side's home form will dictate whether they can mount a sustained challenge for the Barclays Premier League title.

The Gunners head into Saturday's showdown with leaders Chelsea unbeaten this season and 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.
