Arsenal boss Arsene Wenger feels Manchester City can blow their title bid due to their away form.
Arsenal will go back to the top of the table if they beat improving Crystal Palace at the Emirates on Sunday and will stay there if City slip up against Chelsea on Monday.
Wenger believes City's fragility on the road could be pivotal.
"They are the team of the moment so everybody is drawing definite conclusions,' said Wenger. 'I don't deny their strength, quality and the exceptional players they have. But let's not forget they have lost four away games."
