Bertrand Traore scored a brilliant goal on his Aston Villa debut as they beat Bristol City in the Carabao Cup.
They host another Championship side, Stoke City, in the fourth round next week.
Anwar El Ghazi put Villa ahead after good work by Keinan Davis and Traore hit a wonderful side-footed volley from Jacob Ramsey's pass.
Club-record signing Ollie Watkins scored a third from a Trezeguet pass.
Former Chelsea forward Traore joined Villa for £17m from French side Lyon last week.
Dean Smith's side, who lost last season's final to Manchester City, were good value for their win.
