Stoke will have to be "very disciplined" if they are to claim another Premier League scalp in the Carabao Cup, says boss Michael O'Neill.
Having won 1-0 at Wolves in the second round, Championship side Stoke meet in-form Aston Villa at Villa Park for a place in the quarter-finals.
"We particularly enjoyed the game against Wolves," added O'Neill.
"We had to be very tactical and very disciplined. We'll have to be the same again against Villa."
Villa reached last season's final and have already won away at League One Burton and Championship Bristol City in the second and third rounds of this season's competition respectively.
