Chelsea sealed a place in the fourth round of the FA Cup as John Obi Mikel and Oscar scored in a 2-0 victory at Derby.
Mikel broke the deadlock after 66 minutes after getting on the end of a wicked delivery from Willian and nodding the ball into the net.
Oscar then secured progression five minutes later as he rifled a swerving strike inside the near post.
