Grealish comes on to add the finishing touch as Villa progress
Brighton 1 Aston Villa 3
Aston Villa cruised into the Carabao Cup fourth round, with substitute Jack Grealish sealing a comfortable 3-1 win over a young Brighton side.
First-half goals from Jota and Conor Hourihane saw Villa seize control of the all-Premier League clash at the Amex Stadium.
A header from 17-year-old defender Haydon Roberts gave the inexperienced hosts hope of forcing a penalty shoot-out, before Grealish slammed home a powerful half-volley to put the result beyond doubt.
Villa went ahead with 22 minutes played when creative Spaniard Jota fired home a first-time finish after Albion goalkeeper David Button pushed away Hourihane's fizzing cross.
Brighton fell further behind in the 33rd minute as Hourihane applied the emphatic finishing touch this time by dispatching Keinan Davis' pull back.
Roberts reignited the game by nodding home a right-wing corner in the 61st minute, but Grealish, on for the final 24 minutes in place of John McGinn, settled the contest 13 minutes from time by smashing in from the edge of the box.
