"Toby Alderweireld runs in on that header and he just looks like he's got more purpose about what he's doing. You've got to want to make things happen and that's been the difference today."
Nearly the third for Shane Long. Fellow strike partner Graziano Pelle works hard to win the ball back before launching it high into area, but Long can't get enough on the volley and it runs wide of goal. Still plenty of time to complete his treble.
Ooh, beauty of a ball into the box from the impressive James Ward-Prowse. It's flicked on by Toby Alderweireld but pushed away by Shay Given. The ball was creeping in, you know. Turns out to be a good stop.

"Southampton are in well-regimented lines every time they lose the ball and have to defend. It's only Graziano Pelle who is in Villa's half. It's like a bow and arrow. Every time you fire an arrow, you have to reload as quickly as possible otherwise you're going to be in trouble."
Alan Hutton tries to curl one into the top corner from the edge of the box..
..but gets it horribly wrong, finding row Z. Not good!

Charles N'Zogbia is hooked and is replaced by Gabriel Agbonlahor.
Manager Tim Sherwood is allowed only three changes, but he if could make 11, he would!
Ronald Koeman sits on the Southampton bench next to his brother Erwin. The duo have done a marvellous job at St Mary's this season. Most successful footballing siblings since Gary and Phil Neville?
Even at the back, Southampton are fighting, trying to give nothing away. They are not taking this lightly, even though they have a four goal advantage. Jose Fonte crunches into a tackle which is warmly applauded by the fans.

"This is bizarre, some of the things I've seen today. I've never seen the likes of Ron Vlaar perform like they have today. There's rumours of bigger clubs coming in for him, but not on today's performance."
Southampton are sniffing and it won't be surprising if they get more goals here. Remember, Shane Long is on a hat-trick..
Peerpresha:, external Dropped my pen at 0-0, picked it up 1-0, sat up 2-0, rubbed my eyes 3-0, widened eyes 4-0, dropped jaw 5-0, left the room 5-1.
A hairy moment for Shay Given, as he decides to come for a cross for the first time in his career, which he makes a hash of, nearly gifting another goal. Should have stayed at home.
Brilliantly whipped in corner by youngster James Ward-Prowse, which is flicked away for another, but it comes to nothing.
Corner for Southampton, and there is some wrestling going on in the box, with illegal tactics being used to stop Sadio Mane. Well, they have to do something.
Free-kick in an inviting position for Aston Villa and is it swung in by Charles N'Zogbia..
..but a poor, poor delivery. They won't get back into the game with crosses like that.
Oh, Aston Villa have come back. They kick off in the second half. How many more goals will we see?
Love it! Southampton fan Craig David, external (yes, THE Craig David) has tweeted: My mum got this birthday gift right!
Image source, Craig DavidThe big question is, will Aston Villa return for the second half? Can they just tell the referee, 'We don't want to play any more' and go home?
Dan, London: Good work Southampton. Good to put this "Sherwood is a genius" utter nonsense to bed.
