The Blues head into tonight's second leg with a three-goal deficit to overturn following last week's 5-2 defeat in Paris.

Injuries to Filip Jorgensen and Reece James meant there were always going to be at least two alterations to the side that lost in the French capital and there are also four changes compared to that first leg line-up.

As was the case for Saturday's defeat to Newcastle United, Robert Sanchez starts in goal and tonight he will be protected by a back four of Trevoh Chalobah, Mamadou Sarr, Jorrel Hato and Marc Cucurella.

Moises Caicedo and Andrey Santos are set to line up in midfield, with Cole Palmer, Enzo Fernandez and Pedro Neto expected to play behind frontman Joao Pedro.

A strong Chelsea bench includes attacking talent Estevao Willian, Alejandro Garnacho, Liam Delap, Marc Guiu and talented Academy players Ryan Kavuma-McQueen and Shim Mheuka.

Chelsea: Sanchez; Chalobah, Sarr, Hato, Cucurella; Caicedo, Andrey Santos; Palmer, Fernandez (c), Neto; Joao Pedro

Substitutes: Merrick, Sharman-Lowe, Acheampong, Tosin, Fofana, Lavia, Kavuma-McQueen, Estevao Willian, Garnacho, Delap, Guiu, Mheuka
