Villa boss Dean Smith: "I try to defend the players but today was not good enough. We got what we deserved.
"We spoke about having a good start but in the first 20 minutes we never laid a glove on them. They were miles off it in the first half.
"Last week against Tottenham gave me a lot of heart then today, dreadful. We can't play that bad again.
"It has to be the lowest of the low. The defeat at Watford (3-0 in December) was bad but this was on a par."
Southampton manager Ralph Hasenhuttl: "It was very important to show a reaction after the last home game and the way we started was what we wanted to do today.
"We had 28 shots and that shows how dominant we have been. It was a fantastic atmosphere and the guys enjoyed it. It's important to have a fortress here again."
