Aston Villa have advanced to the Carabao Cup fourth-round with a 3-1 win over Brighton.
Diogo Jota, Jack Grealish and Conor Hourihane were on target for Villa, while 17-year-old Haydn Roberts pulled one back for the hosts, who made 11 changes for the match.
Speaking after the game, Villa boss Dean Smith said: "As a Villa supporter, I've seen teams that have come unstuck in situations like that, whether it's a youthful team or a lower-league team.
"The words I said to them were attitude, application and teamwork and I thought we got that in abundance tonight and they have done it right.
"This football club has got a very proud history in all cup competitions - we've won this five times, we've won the FA Cup seven times.
"You've seen the numbers that have travelled down from Birmingham and they deserve our utmost respect - and we've given it that tonight."
