Chelsea 5-0 Morecambe: Enzo Maresca's side strolled out comfortable winners against the League Two strugglers at Stamford Bridge.
The Blues had a golden opportunity to take an early lead through Christopher Nkunku but the Frenchman was unable to convert his penalty on 17 minutes.
Chelsea got their lead before the interval however, as summer signing Tosin Adarabioyo put them in front.
Nkunku made it 2-0 on 50 minutes, before Adarabioyo added a third.
Substitute Joao Felix came off the bench to complete the rout in the closing stages, netting twice in quick succession as Chelsea booked their place in the FA Cup fourth round.
