Six days after thumping AC Milan 3-0, Chelsea will travel to San Siro to try and replicate the feat.
The Blues, who beat Wolves 3-0 at the weekend, have climbed up into second in their Champions League group but still have a whole lot of work to do to ensure they book their place in the knockout stages.
With a handful of injury concerns to address, here’s how Graham Potter could set up.
GK: Kepa Arrizabalaga – The Spaniard appears to have Potter’s faith right now, but he’ll need to keep the levels up as Edouard Mendy is back from injury.
CB: Trevoh Chalobah – Restored to the team after Wesley Fofana’s knee injury last week, Chalobah’s record of never losing when he starts remains alive.
CB: Thiago Silva – Silva was sensational against Milan and was given a rest at the weekend to ensure he’s ready for this one.
CB: Marc Cucurella – Cucurella shone in the centre-back/left-back hybrid role against Wolves but might have more of a concrete spot against a side capable of causing real problems.
RM: Reece James – Cesar Azpilicueta was sensational against Wolves but, let’s be real, there’s no way James doesn’t start this one.
CM: Conor Gallagher – Another who shone at the weekend, Gallagher is quietly emerging as a key part of Potter’s setup.
CM: Mateo Kovacic – Kovacic has the big-game experience which may give him the edge of Ruben Loftus-Cheek, but don’t be surprised to see the latter given significant minutes off the bench.
LM: Ben Chilwell – Rested last time out, Chilwell deserves to return to the starting XI, but Potter is right to manage his minutes.
AM: Mason Mount – Two assists against Wolves will likely force Mount’s way into the starting lineup.
AM: Raheem Sterling – We’re yet to see Sterling return to the wing-back role that he was given in Potter’s first game, despite the fact he actually did pretty well.
ST: Pierre-Emerick Aubameyang – Despite the fact Kai Havertz scored against Wolves, Chelsea need someone with more natural ruthlessness, and Auba is the only man in the squad with that tough streak.
