Mauricio Pochettino's side booked their place in the fourth round of the FA Cup on Saturday afternoon after sealing a 4-0 victory against Preston at Stamford Bridge.
The Blues started the game in second gear, allowing Preston several chances while missing many of their own, with Enzo Fernandez and Cole Palmer both coming close in the first 45 minutes.
After a goalless first-half, the Blues found their ryhthm, with Malo Gusto playing in a fine cross to Armando Broja, who's glancing header saw Chelsea break the deadlock.
