Leicester ease Claudio Ranieri's worries

The champions, in a welcome break from their Premier League form, needed extra time to see off their Championship opponents and goals from Onyinye Ndidi and then Demarai Gray in the additional half an hour did the trick to set up a trip to Millwall in the fifth round later this month.
Andy King, captain for the night, headed Leicester in front at the start of the second half but Abdoul Camara’s deflected free-kick brought Derby level just after the hour.
