Cardiff head coach Brian Barry-Murphy makes five changes from Saturday’s 4-3 win over Doncaster Rovers in League One.
Top scorer Yousef Salech is on the bench and replaced by Callum Robinson, who has scored five goals in his three Premier League appearances against Chelsea.
Right-back Ronan Kpakio is suspended so Perry Ng comes in, while Wales centre-back Dylan Lawlor and midfielders Joel Colwill and David Turnbull are recalled.
Will Fish, Alex Robertson and Omari Kellyman – who is ineligible as he is on loan from Chelsea – are the other players to drop out.
There’s also a 15-year-old, Axel Donczew, on the bench. He already has a senior appearance to his name, making him Cardiff’s youngest player of all time.
Cardiff starting XI: Trott; Ng, Lawlor, Chambers, Bagan; Wintle, J. Colwill, Turnbull; Ashford, Davies, Robinson.
Subs: Turner, Giles, Fish, Mafico, Robertson, Donczew, Nyakuhwa, Willock, Salech.
Chelsea boss Enzo Maresca has changed his entire team from the 2-0 Premier League win over Everton on Saturday.
Cole Palmer is rested and Marc Cucurella is suspended but there’s no shortage of quality and experience in this line-up.
Moises Caicedo returns to captain the team, while there are starts for the likes of Marc Guiu and Facundo Buonanotte.
Chelsea starting XI: Jorgensen, Acheampong, Badiashile, Tosin, Hato, Andrey Santos, Caicedo, George, Buonanotte, Gittens, Guiu.
Subs: Sanchez, Gusto, James, Chalobah, Fofana, Fernandez, Garnacho, Neto, Joao Pedro.
