Chelsea captain Cesar Azpilicueta knows they'll face a motivated Arsenal on Sunday eager to impress new manager Mikel Arteta.
Azpilicueta concedes Arteta's recent appointment will be a factor.
He said, "I have never played with Mikel Arteta.
"I know him because he is Spanish and he played for Arsenal but I don't have any special relationship with him. For Arsenal it is a new beginning with a new coach but for us it is a massive game after losing against Southampton.
"It is a London derby and obviously we have to bounce back after the disappointing Boxing Day (defeat to Southampton)."
