Southampton fought back from 2-0 down to beat Burnley and claim a crucial three points in the battle for Premier League survival.

Chris Wood fired in an early penalty, awarded after the video assistant referee advised Andre Marriner to check the pitchside monitor, before knocking down Ben Mee's long ball for Matej Vydra to volley in a fine second goal.

But Southampton, who welcomed back Danny Ings and Theo Walcott from injury, hit straight back with midfielder Stuart Armstrong sweeping in the ball after a neat flick by Ings.

The ex-Burnley striker coolly slotted in his 10th goal of the season to equalise just before half-time, scoring against his former club for the third successive game.

And although Burnley's Nick Pope pulled off some fine saves after the break, Saints broke the England goalkeeper's resistance as Nathan Redmond volleyed them in front.

The hosts then needed some goalkeeping heroics from former England keeper Fraser Forster, who twice denied Wood late on, before clinching just their second win in 13 Premier League games.

Southampton boss Ralph Hasenhuttl said afterwards, "A difficult start for us, and normally an opponent that is not helpful if you go two down. I'm very happy to see things we were working on over the last two weeks - our decision-making in the final third was fantastic. We could have scored five or six or more goals against a team that doesn't normally give you many chances.

"It was a deserved win. We tried to keep the tempo very high and stretch them all the time and it worked. We have belief in what we are doing and I think you grab the chance when you get it.

"It was important to make the equaliser before half-time. Then you are in a better position mentally to keep on going. I don't know a lot of teams who turned it aournd like we did, so it's a massive boost.

"It was a six-pointer today. To turn the tables around is amazing for us and I think the guys did a good job today."
