Blues ease to extend lead over the Gunners.
Former Arsenal man Cesc Fabregas returns to haunt the Gunners with fine through-ball to goal machine Diego Costa.
Fabregas has already provided a raft of assists since moving back to the Premier League but this one against Arsenal may be his best of 2014/15 thus far.
His long range pass dissected the Arsenal back-line and Diego Costa did the rest.
