Pep Guardiola is tonight expected to deploy a false nine as Manchester City look to beat Chelsea and reach the FA Cup final.
Sergio Aguero has been ruled out of the game due to an ongoing muscular problem, leaving Gabriel Jesus as the only striker option.
Thomas Tuchel, on the other hand, will be without the injured Mateo Kovacic and Andreas Christensen.
Here are the confirmed lineups:
Chelsea XI | Mendy; Azpilicueta, Silva, Rudiger; James, Kante, Jorginho, Chilwell; Ziyech, Mount; Werner
SUBS | Caballero, Alonso, Emerson, Zouma, Gilmour, Havertz, Hudson-Odoi, Pulisic, Giroud
