Olivier Giroud scored twice as Chelsea saw off PAOK Salonika to secure top spot in Europa League Group L.
The Frenchman curled home from Pedro's pass before burying a volley from Cesc Fabregas' lofted through ball to give the hosts a two-goal lead at the break.
The Greek visitors had been down to 10 men since the seventh minute with Yevhen Khacheridi dismissed for diving in and denying Giroud a clear goal-scoring opportunity.
