Frank Lampard is content with his full-back options despite key player injuries.
Reece James and Ben Chilwell are ruled out for Chelsea’s trip to the Emirates on Saturday.
Chilwell suffered an ankle injury when he collided with Jarrod Bowen in Chelsea’s 3-0 win over West Ham.
Reece James is also out with a knee injury and Lampard was pleased with Azpilicueta and Emerson Palmieri’s performance at Stamford Bridge.
“A slight difference in attributes can change things to a degree but I don’t expect too much because they are accomplished players,” Lampard said.
“The captain of the club, Azpi, did brilliantly (against West Ham) in all senses of his game, particularly the defensive side which was so important in the way they play.
“Emer did well as well. When we train we work inclusively as a whole squad and know the movements we want to make. We’ll prepare for Arsenal and onwards with our attacking plan.
“We want to attack with our full-backs, they know that. Reece and Chilly have been doing really well, we hope their injuries are not that bad and they will be in and around the games over Christmas, so we’ll see.
“But I was pleased with the two lads, they were comfortable.”
