After this hard-fought Fifth Round victory at Championship Wolves - courtesy of second-half strikes from Pedro and Diego Costa - Antonio Conte's men are now just three wins from lifting the FA Cup.
The different line-up initially struggled to contain a Wolves side who had knocked Liverpool and Stoke out of the FA Cup on route to their tie with Chelsea on Saturday.
Chelsea drew 1-1 at Burnley last Sunday, but Conte was determined his side would not suffer the same cup fate as the Clarets, beaten earlier in the day by non-League Lincoln.
"I played with world-class players, I played against world-class players and Chelsea have got that".

"This is a great achievement for them and also this is the beauty of football and the FA Cup", he said. Antonio Conte introduced Cesar Azpilicueta from the bench in place of Pedro, evidently looking to take any sting out of the game. "This is not true and we must pay attention, because we must fight for 13 games and to have the will to fight, to win is very important".
