Arsenal manager Arsene Wenger has made just one change to his starting lineup for the second leg of the EFL Cup semi-final with Chelsea.
On Saturday afternoon, Arsenal scored four times in the opening 22 minutes of the Premier League fixture with Crystal Palace, and Wenger has opted to keep the same 10 outfield players from that game.
Nacho Monreal has successfully recovered from an ankle knock, so the only alteration sees David Ospina take Petr Cech's place between the sticks.
Aaron Ramsey is also available again having been forced to sit out the weekend's fixture in North London, and the Welshman is likely to be used off the bench during the second half.
Chelsea head coach Antonio Conte has opted to recall Pedro after the Spaniard served a one-match ban, with Michy Batshuayi having to make do with a place among the replacements.
Andreas Christensen is fit despite sustaining a head injury against Brighton & Hove Albion, while Gary Cahill is able to return to the substitutes' bench after a hamstring problem.
Ross Barkley could also make his Chelsea debut after being selected on the bench.
The first leg at Stamford Bridge ended in a goalless draw and like the game in West London, VAR will be available to the officials.
Arsenal: Ospina; Bellerin, Mustafi, Koscielny, Monreal; Elneny, Xhaka, Wilshere; Iwobi, Ozil, Lacazette
Subs: Macey, Chambers, Kolasinac, Maitland-Niles, Ramsey, Nelson, Nketiah
Chelsea: Caballero; Azpilicueta, Christensen, Rudiger; Moses, Bakayoko, Kante, Alonso; Willian, Hazard, Pedro
Subs: Eduardo, Cahill, David Luiz, Zappacosta, Drinkwater, Barkley, Batshuayi
