Chelsea had to wait over an hour before they broke the deadlock against a very determined Wolverhampton Wanderers, thanks to Pedro Rodriguez and Diego Costa.
The FA Cup fifth round tie at the Molineux Stadium was a classic as the hosts matched the former Premier League champions in every department and would have taken the lead as early as the 5th minute when George Saville hit the wood work.
It was a midfield affair in the first 45 minutes as both teams sought for the opener to no avail.
Chelsea ran riot right from the start of the second half and were obviously the better side before the home side crumbled in the 65th minute when Pedro headed home from close-range.
Diego Costa wrapped it up in style with a brilliant strike in the box to earn Antonio Conte’s side a deserved quarter-final berth.
Meanwhile, the most surprising result of the day came from Lincoln FC which knocked out Premier League side Burnley out of the competition.
Sean Raggett scored the stunner one minute from time to earn his side a quarter-final slot.
Burnley 0 - 1 Lincoln
Huddersfield Town 0 - 0 Manchester City
Middlesbrough 3 - 2 Oxford United
Millwall 1 - 0 Leicester City
