Antonio Conte's unbeaten competitive record with Chelsea could be at risk on Saturday, as they welcome Burnley, who will be looking to claim another big scalp at Stamford Bridge.
Perfect start to life at the Bridge
It has been a perfect start to life under Conte for the Blues, especially if you were to compare it to last season.
Conte was brought in to take the helm, and has proven a great addition, winning their first three games of the season - including back-to-back wins in the Premier League.
It took late goals from striker Diego Costa, to win both their league matches 2-1, against West Ham and Watford respectively.
Many would of thought that they would have steam rolled Bristol Rovers in the Football League Cup midweek, but it was far from what was expected.
Michy Batshuayi scored 29 minutes into his full debut, before Victor Moses added second moments later, with a Peter Hartley header giving Rovers hope.
Batshuayi looked to have wrapped up the tie with his second, Ellis Harrison shook nerves with the visitor's second goal, but the Blues held on for the 3-2 win to set up a tie with Premier League champions Leicester City.
The start many wouldn't have expected
It only took a season for Sean Dyche's side to return to the top-flight, but with the lack of signings, and the opening defeat to Swansea City, many expected a similar struggle this time around.
However they shocked many, with goals from Sam Vokes and Andre Grey to give them a shock 2-0 win over early pace setters Liverpool.
However they were brought back down to earth midweek when they took on Accrington Stanley. The game looked to be going the distance at the Crown Ground, until a late strike from Matty Pearson secured a tie with West Ham for the lower league minnow.
