It was a comfortable and easy progression to the fourth round for the Blues, who beat non-league Chesterfield 5-1 at home at the start of the year.
The blues looked to continue their fairytale as they take on Plymouth Argyle at Stamford Bridge.
The 2021 runner-up made a strong start to the game, with three decent chances in the first few minutes alone, but it were the visitors who took the lead with Macaulay Gillesphey opener who headed into Kepa’s net from a set piece.
Chelsea look to level terms almost immediately. Unfortunately, Mateo Kovacic hit the crossbar and would also hit the post later on in the half. Hudson-Odoi also drew woodwork before Azpilicueta finally brought Chelsea level just before the first half with a classy backheel flick.
Chelsea ratched up the pressure a bit more,with Lukaku missing a tap-in, then Azpilicueta scored an offside goal, Ziyech and Havertz also missed the target to put Chelsea in front.
Chelsea were unable to find a breakthrough in the second half, which sees the game go into extra-time, were Chelsea had a lot of missed chances same in the 90 minutes.
Eventually, all of Chelsea’s pressure paid off, with Havertz and Alonso combining wonderfully to take the lead for the first time all game.
There was still time for drama at the end, with Chelsea giving away a silly penalty, but Kepa became the hero making the save on the spot kick, to prevent the game from going to spot kicks just a few minutes to the end of the game.
