Football: Cazorla warns Arsenal not to be complacent against Marseille

LONDON (REUTERS) - Arsenal's path into the Champions League knockout rounds looks to be a safe one with a home game against rock-bottom Olympique Marseille coming up tomorrow but they are taking nothing for granted.

The Londoners top Group F with nine points from four matches, the same as second-placed Napoli and three more than Borussia Dortmund.

Should Arsenal beat Marseille and Dortmund fail to defeat Napoli, Arsene Wenger's side would be guaranteed to qualify with a game to spare.

Midfielder Santi Cazorla has warned against slipping up, especially with a trip to Naples concluding the group stages.

"The main problem I see is everyone thinks it's going to be an easy game for us to win," the Spaniard told the club's website.

"There is nothing at stake for Marseille because they have zero points but they are going to make things difficult for us. It may be tough and if we're not careful, we might slip up and then we might not be able to get through to the next round."

With little chance of even finishing third in the group, Marseille may elect to field a weakened side at Arsenal.
