As reported by Simon Johnson of the Evening Standard, Chelsea captain John Terry is set to return to the starting lineup for Saturday's trip to Hull City.
Terry trained with the squad yesterday and is ready to return for the trip to Hull as Conte looks to find a solution to their problems.

Terry had been nursing a sprained ankle since the 2-2 draw at Swansea City, and while Chelsea's defense hadn't exactly been impregnable prior to that point either (6 goals conceded in 5 games with 1 clean sheet), it's been even worse since (7 goals conceded in 3 games with 0 clean sheets).
Presumably, Calamity Cahill will drop to the bench, reuniting JT and David Luiz for the first time since Boxing Day 2013 and a 1-0 win over Swansea City, a game perhaps more notable for being Juan Mata's final game for Chelsea at the Bridge.
A three-back system is another option that keeps popping up in rumors and speculations, and is perhaps a desperation option for Conte after trying it out (as a 3-4-3) for most of the second half against Arsenal.
