Marseille could make life difficult, warns Arsenal midfielder Santi Cazorla

Arsenal midfielder Santi Cazorla has warned his side they cannot afford to take Marseille for granted when they meet in the Champions League tomorrow.

The Gunners path into the knockout rounds looks to be a safe one with a home game against the rock bottom Olympique Marseille. 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.

However, Cazorla has warned against complacency 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 said. "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.

"We need to understand it's a vital match," said Cazorla. "If we obtained a bad result then it would make things very complicated for us to go to Napoli and win there."
