Southampton boss Russell Martin was left frustrated about his side’s “nonsense” performance despite a dramatic last-gasp 3-2 victory over Watford.

Leicester and Leeds lost this weekend, while Ipswich dropped points to give Saints renewed hope of an automatic promotion spot and an immediate return to the Premier League.

They needed a stoppage-time winner from Flynn Downes to beat the Hornets after throwing away a two-goal lead.

And Martin said: “It’s a good day for us in the end with the results elsewhere as well, but we can only focus on ourselves and I’m pleased we got over the line.

“I’m frustrated with how long it took and what it took, but I’m really pleased we won. We played some brilliant football with plenty of running and energy.

“The feeling at the end is amazing, but it just shouldn’t be that. Watford were good, and they’re playing with freedom and they’re running so hard for Tom.

“We have five games now where we just can’t afford to play like that. Unfortunately for us, we’re not in the top two and having a nice time. We’re fighting and chasing for everything we have.

“I’m frustrated about some of it but really pleased with some of it. I’m delighted with the character and the grit and the willingness to win.

“You can’t concede two goals again at home after being two up – we have to stop that nonsense.

“I’ve never stopped believing in the group of players that we have. I think they’ve shown they believe so much in what they’re doing with the late winner today and the fight.”

Saints were in cruise control after Will Smallbone had headed in their fastest goal of the season after 57 seconds and Che Adams had doubled the lead by tapping in David Brooks’ cross.

Ryan Porteous pulled one back for the Hornets before the break before they thought they had earned a fifth straight draw when Ismael Kone coolly slotted in an 85th-minute equaliser.

But West Ham loanee Downes bundled in at the back post with the last kick of the game to send St Mary’s into chaos.

Watford interim boss Tom Cleverley said: “The red card incident on Porteous, genuine mistake. The handball, his line of sight might have been obscured, genuine mistake.

“The fact that the corner gets delivered after the 98th minute after seven added on is a worry.

“For me, our season is sort of mid-table and it’s not affected the way our campaign ends so much, but when there’s hundreds of millions of pounds on the line for Leeds, Ipswich and Leicester.

“I think they could be arguing that the top referees should be in charge of these games for when the stakes are so big.

“I will never, ever have a go for genuine mistakes. I’m disappointed the corner was taken. There was no subs, no goals in injury time.

“It’s a really difficult one to take. But for the first time we’ve been behind in my stint as manager and we showed real character to come back.

“It feels a really, really bitter pill to swallow that we’ve come out with no points. We’re feeling really hard done by now.”

Flynn Downes sensationally bundled in a stoppage-time winner to keep Southampton in the Sky Bet Championship automatic promotion race with a 3-2 victory over Watford.

Will Smallbone and Che Adams had put Saints on course to capitalise on Leeds and Leicester’s earlier defeats before Ryan Porteous and Ismael Kone levelled things up.

But Downes crashed home at the back post deep into stoppage time to send St Mary’s and manager Russell Martin into raptures – with a play-off place confirmed at the very least.

Saints are now seven points off the top two with games in hand.

Saints were rapid out the blocks as Smallbone headed in their quickest goal of the campaign after 57 seconds.

Adam Armstrong provided a perfect cross from the left side to allow Ireland international Smallbone to celebrate his fifth goal of the season.

The midfielder almost bagged a quickfire brace when he won the ball with a tackle on the edge of the Hornets box before getting back to his feet to blaze over the crossbar.

The home supporters did not have to wait too long for a second goal, though, as Adams tapped home in the 20th minute.

His 15th goal, and third versus Watford, this season came after Kyle Walker-Peters’ cross was sliced by Tom Dele-Bashiru, with his clearance chased down by David Brooks to tee up the Scotland international.

The momentum suddenly turned towards Watford half an hour into the match with Yaser Asprilla twice shooting wide, the second after a skilful run off the right flank.

They capitalised in the 34th minute when lackadaisical defending saw Porteous pick up the ball and fire home, via a deflection off Jack Stephens.

Vakoun Bayo stabbed another Hornets chance wide as Saints’ advantage was almost completely wiped out.

But the hosts rallied either side of the interval. Adam Armstrong controlled and fired over a Joe Aribo lifted ball, before Brooks slapped over a first-time effort from the edge of the box.

Porteous almost notched for a second time in the 53rd minute but his header was cleared off the line by Taylor Harwood-Bellis, before Giorgi Chakvetadze sliced wide from six yards.

Ryan Fraser thought he had settled the nerves when he slotted home in the 83rd minute but had not timed his run from Armstrong’s through ball.

And his poor synchronisation was punished when Kone turned on the ball in midfield before driving into the box and coolly inserting into the bottom corner – which appeared to put Watford on course for a fifth straight draw.

Armstrong almost won it when he volleyed into the ground, but Daniel Bachmann brilliantly tipped over before Downes’ last-gasp heroics.

The on-loan West Ham midfielder met Harwood-Bellis’ knock-on from a corner to take the three points.

Russell Martin says Southampton’s new unbeaten club record will not carry as much importance if the Saints do not return to the Premier League.

Southampton broke a 103-year-old club record on Saturday by extending their unbeaten run to 21 games with a 3-1 victory at Martin’s old club Swansea.

Victory lifted the Saints into second place in the Sky Bet Championship, above Ipswich on goal difference.

“It is a nice moment,” Martin said after his side completed Southampton’s best unbeaten run in all competitions since joining the Football League in 1920, eclipsing the 20 games undefeated achieved the following year.

“I’m really grateful to the players for what they’ve done, the courage they’ve shown. I’m immensely proud.

“The way they did it in the first half, one of the best performances I’ve ever been involved in as coach.

“It’s taken a lot of hard work and they’ve really stepped up. They’ve written themselves in to the history books – and let’s keep it going.

“It will have more significance, importance and standing if we achieve what we want at the end of the season, otherwise it will be just something we’ve achieved together.”

First-half goals from Che Adams, Will Smallbone and Flynn Downes – his first for Saints coming on his 25th birthday and against his former club – put Southampton in control.

However, Saints had to withstand late home pressure as Swansea twice hit the post and Gavin Bazunu made a couple of useful saves.

“We didn’t mix the game up in the last 20 minutes and played with no real purpose,” said Martin.

“We were relentless in the first half and I was disappointed the way we conceded at the end of that half.

“It was handball and offside but we had one offside (goal), so it is what it is.

“It took us a little bit longer to get the wheels in motion. Those two clubs (Leicester and Ipswich) had the two best starts in Championship history, so the fact we are now there and in the fight, in the mix, and hunting them both down, is a real credit to the players.”

Martin was given a warm welcome by Swansea fans on his return to the club he managed for two years and left last June.

Relations between Martin and the Swansea hierarchy had soured after the club had a dismal January transfer window.

“I felt sick this morning and couldn’t eat any breakfast,” said Martin.

“But it was really nice to come back and I enjoyed it more because of our performance and the fact we won.

“Seeing all the backroom staff and lots of people who meant a lot to us – and who we have a lot of love and affection for – was special.”

For Swansea boss Luke Williams, it was a first defeat in charge following an FA Cup victory over Morecambe and a Championship draw at Birmingham.

Jamie Paterson made it 2-1 just before half-time with a close-range header, and Swansea finally shook off the shackles to set up a grandstand finish that almost brought surprise reward.

“First half we were too deep, far too deep,” said Williams, Martin’s former assistant at both MK Dons and Swansea.

“Southampton could push the ball around, take their time and wait for the space and they did that brilliantly.

“Second half, the difference is we play higher up the pitch and we were able to create chances.”

Former Notts County boss Williams was appointed after Martin’s successor Michael Duff lasted less than five months in the job.

He said: “If it was something that was a really quick fix, everyone would be doing it. it’s not going to be that easy.

“I need to try to get the message across to the players in a clinical way because we are not blessed with time at the moment.”

Adam Armstrong’s brace fired Southampton to a 2-0 victory over Cardiff and to Saints’ longest unbeaten run for 19 seasons.

Armstrong curled and headed in his 11th and 12th goals of the season to stay on the heels of Blackburn’s Sammie Szmodics in the race for the Sky Bet Championship’s Golden Boot.

Saints stay fourth but the 11 matches they are now without defeat has equalled the number they went unbeaten between December 1994 and February 1995 – though that run remarkably contained nine draws, in contrast to the eight wins in the current sequence.

The opener came in the 11th minute to complete a fine team move.

Saints had passed and moved their way down the left flank before Flynn Downes fired in to Carlos Alcaraz, who laid off to Adam Armstrong. The in-form hitman took a touch before bending into the top corner.

Four minutes later the same player doubled the hosts’ lead. This time it was Stuart Armstrong’s quick feet that earned space on the left side of the box before his cross deflected up off Dimitrios Goutas and onto Adam Armstrong’s head.

While chances did not come freely for Southampton, they kept the ball and toyed with the Bluebirds with incisive passes as freezing fog hovered over St Mary’s.

Adam Armstrong almost completed his hat-trick when Che Adams’ cross was pawed into him but his header lacked power and allowed Alex Runarsson to scramble back across his line to hold on.

Alcaraz headed over a Stuart Armstrong centre but the third goal should have gone to the visitors in first-half stoppage time. Perry Ng’s deflected ball into the box found Josh Bowler a couple of yards out and free at the back post, but he skied over the crossbar.

Cardiff had only been behind once before at the break this season, and continued their attempt to a comeback as Karlan Grant fired wide.

Che Adams replied in kind in his first start since October before substitute Joe Aribo squirted a shot against the base of the post.

Ryan Fraser had three good chances to put Saints clear but failed to put either on target before a third effort was deflected wide.

The hosts continued to slice through hapless Cardiff but Runarsson denied Adam Armstrong a third after a rasping drive.

Fraser continued to be frustrated in front of goal while Sekou Mara also had shots as Southampton could have justifiably won by a landslide.

Former Swansea boss Russell Martin continued his 100 per cent win record against Cardiff but saw their promotion position unmoved, with Leicester, Ipswich and Leeds also winning.
