Arsene Wenger: Arsenal have potential to win league

Arsenal manager Arsene Wenger believes his side have the "potential" to compete for the Premier League crown.

The Gunners face Champions League champions Chelsea at the Emirates on Saturday and Wenger says his side face a "big task" and need to be "efficient" to secure all three points.

Arsenal, who have failed to win a trophy in over seven years have been praised by the likes of Real Madrid coach Jose Mourinho for their performances so far this season.
