The Blues are unchanged from the side that beat Wolves in our final Premier League game last weekend.
That means Willy Caballero continues in goal and in-form Olivier Giroud leads the attack against his former club.
Fit-again N'Golo Kante is on the Chelsea bench. There is no Willian. He fought hard to be fit enough but had to drop out of the squad in the past 24 hours.
Another facing his former side is Arsenal's David Luiz who is joined in the Gunners' defence by Rob Holding, replacement for the injured Shkodran Mustafi. Arsenal, like Chelsea, appear to be lining up with a back-three, as in the semi-finals.
Chelsea Caballero; Azpilicueta (c), Zouma, Rudiger; James, Jorginho, Kovacic, Alonso; Mount, Giroud, Pulisic.
Subs Kepa, Tomori, Christensen, Emerson, Kante, Barkley, Pedro, Hudson-Odoi, Abraham.
Arsenal Martinez; Holding, David Luiz, Tierney; Bellerin, Ceballos, Xhaka, Maitland-Niles; Pepe, Aubameyang (c); Lacazette.
Subs Macey, Sokratis, Willock, Kolasinac, Smith, Torreira, Nelson, Nketiah, Saka.
The referee is Anthony Taylor.
