Danny Ings scored against his former club as Burnley's survival chances suffered a huge setback against Aston Villa at Turf Moor.
Ings, who spent four years with the Clarets before moving to Liverpool in 2015, did not celebrate after tucking past Nick Pope, having been put through by Emiliano Buendia.
Argentine Buendia, starting in place of Philippe Coutinho who was dropped to the bench, then scored with a deflected finish after being picked out inside the box by Lucas Digne.
Ollie Watkins added to the home side's misery when he was left unmarked to head the third after John McGinn's cross.
