Some interesting team news on both sides. Chelsea make three changes from Saturday – Edouard Mendy is back in goal, while Ben Chilwell and Christian Pulisic come in for Marcos Alonso and Hakim Ziyech. There’s no Kai Havertz, not even on the bench, because of an unspecified injury.
Marc Albrighton replaces the injured Jonny Evans for Leicester, while James Maddison is surprisingly preferred to Kelechi Iheanacho. That probably means a switch to 3-4-2-1, though the flexibility of Albrighton and Castagne means they could also play 4-2-3-1.
Chelsea (3-4-2-1) Mendy; James, Thiago, Rudiger; Azpilicueta, Kante, Jorginho, Chilwell; Mount, Pulisic; Werner.
Substitutes: Arrizabalaga, Alonso, Zouma, Emerson, Kovacic, Ziyech, Abraham, Giroud, Hudson-Odoi.
