Aston Villa captain Jack Grealish scored with a fine late volley as his side came from behind to reach round three of of the Carabao Cup by knocking out League One side Burton Albion.
Home defender Colin Daniel stung Villa with his first goal for the club after just 64 seconds to create hopes of another upset, like two seasons ago.
But £28m record signing Ollie Watkins levelled on 37 minutes, on his debut.
Then, after Grealish's strike, striker Keinan Davis got an injury-time third.
Burton, who beat Villa 1-0 at the Pirelli Stadium at the same stage of the EFL Cup two seasons ago, made four changes from Saturday's 2-1 defeat at Fleetwood.
