Southampton striker Charlie Austin to BT Sport: "It's a special night for me, my debut in the competition. But more importantly it's a good win for the team to get spirits up. We haven't had a great start to the season."
On his argument with Dusan Tadic, on who should take the penalty: "I'm a centre forward, I think I should take the penalties. I was feeling confident.
"It was a bit silly from me and Dusan but I think I'll take the penalties in the future. It's all about the team."

Sparta substitute Matej Pulkrab catches James Ward-Prowse late and is booked. Ward-Prowse was livid with the challenge. Not long to go now.
Southampton want a penalty as Maya Yoshida is barged over by Mario Holek but they don't get one. They can't complain too much though as they should never have had the penalty which gave them the lead early on.
Southampton haven't got behind Sparta's defence much but they breach it here as Pierre-Emile Hojbjerg slips a great pass into Cuco Martina, who waits and waits for someone to cross it into but he dawdles too long and loses the ball.

Martin Frydek has the ball out left for Sparta. But will he shoot or cross? Well I'm not actually sure - but whatever it was, it's high and wide and out for a goal-kick.

Sparta Prague bring on teenage striker Matej Pulkrab for Josef Sural - 15 minutes for him to make himself a hero.
Southampton break at pace but the ball just won't land right for Shane Long to take it in his stride after he flicks it over a defender. Instead he backheels it to Nathan Redmond but the pass is cut out.

Al Jessop: I'm a Saints fan watching from a campsite in Spain. Lots of buffering but it's worth it!
Marius Hollenga: I can say, genuinely, that the Europa League is my favourite football tournament. Great fun.
As I write that David Lafata forces Fraser Forster into a proper save on the half-volley from 20 yards out.
And Nathan Redmond is warning up for the Saints now, who might realise they can't relax too much.
