Unai Emery couldn't have asked for a tougher start to life as Arsenal manager as hot on the heels of defeat to Manchester City in his Premier League bow, the Gunners travel to Chelsea today.

Arsenal's title challenge was laid bare as City cruised to a 2-0 win at the Emirates. However, Emery vowed to stand by his principles despite opening loss. "You shouldn't change your mentality if you lose the first game. I want consistency," said Emery.
