Southampton boss Ralph Hasenhuttl, speaking to Match of the Day: "It's not nice to lose like this. But you know football is not always fair. Today we did not deserve to lose.
"They told me the penalty decision in the first half was a goal if it did not hit the hand. These moments can be decisive if you go 1-0 up.
"We created more chances. Twenty shots on goal is not bad in 90 minutes. We are missing the clinical edge and maybe at the end a bit of luck.
"We had a time in the season where we scored easily. Now there's always a block or a goalkeeper makes a great save. At the moment there are injuries too. We have to find a way out of this."
Aston Villa boss Dean Smith: "We didn't change the team from the other night against Burnley. I thought the lads had played well enough to keep the shirt and they put some effort into today's performance.
"We are on the positive side of some tight decisions this time which is pleasing and it was a quality goal.
"We'd done enough to win that game and we came here to be hard to beat. Some resolute defending at times. A fantastic goal to see."
