Brentford have made two changes from the side that defeated Watford, with Mads Bech and Mathias Jensen coming in.
Yoane Wissa and Bryan Mbeumo keep their places from that night, with Ivan Toney and Marcus Forss on the substitutes bench.
Sergi Canos returns from suspension and returns to right wing-back, whilst Rico Henry keeps his place on the left flank.
With five substitutes being permitted in the competition, the likes of Toney and Forss will be eager to take to the pitch along with Fin Stevens and Myles Peart-Harris, the latter whom arrived from Chelsea in the summer.
Brentford team vs Chelsea: Fernandez; Mads Bech, Jansson, Pinnock; Canos, Baptiste, Jensen, Janelt, Henry; Wissa, Mbeumo.
Subs: Cox, Thompson, Norgaard, Forss, Ghoddos, Onyeka, Toney, Peart-Harris, Stevens.
