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.
Chelsea are the most successful side in the FA Cup since the turn of the century, reaching nine finals (including this season) and winning six of them. We are playing in our third FA Cup final in the past four seasons.
For third time in the last four seasons, Chelsea and Arsenal end the season playing each other in a cup final.
Chelsea and Arsenal have won a combined 12 of the past 20 FA Cup finals (six each).
Chelsea are unbeaten in three games against Arsenal since the Gunners’ 2-0 home Premier League win in January 2019.
This is the 15th time Chelsea and Arsenal have been drawn together in the FA Cup. The Blues have won five and Arsenal nine of the meetings so far.
However, the semi-final in 2009, thanks to goals from Florent Malouda and Didier Drogba, is the only victory in our last nine encounters in the competition since 1947.
Chelsea play Arsenal for the 201st occasion in all competitions, more times than we’ve played against any other club.
Frank Lampard is hoping to be the first English manager to win a major trophy with Chelsea since Dave Sexton (1971 Cup Winners’ Cup).
As a player, Frank Lampard won four of his five FA Cup finals for Chelsea.
Olivier Giroud has scored in eight of his past nine starts for the Blues including the last six.
