The Gas are more than capable of taking advantage should Conte's side take this one easy.
Chelsea v Bristol Rovers - Tuesday 19:45
Antonio Conte doesn't strike you as the sort of bloke who would accept slipping out of a cup competition with barely a whimper but it's too early in his Chelsea tenure to be sure that he is immune to an upset against a determined Bristol Rovers side. Split a point between the away win at 17/2 and the draw at 20/1.
This isn't necessarily a question of Chelsea's attitude, more a concern about their cohesive quality in depth. Conte will be tempted to rotate, taking the opportunity to look at several players he hasn't seen in competitive action yet, but the Blues have struggled over the past couple of years whenever deprived of key individuals.
There's no real conviction about Rovers to cause a giantkilling, the draw is by far the more confident of the two picks, in which case you'd still fancy Chelsea to prevail. But everything has its price and 20/1 about the Gas crosses that threshold, especially given the similarities between them and the Bradford side that triumphed at Stamford Bridge in the FA Cup two seasons ago.
Darrell Clarke's men aren't overawed by reputations, they are ultra-masculine and fully equipped to deal with the mental side of a challenge on this scale. They might come up short in terms of ability but if Chelsea simply go through the motions, the Gas will compete ferociously for second balls and do everything in their power to ensure it's a long night.
