The journey back up the M3 will be a somewhat sombre one for the Watford contingent.

This latest defeat leaves Quique Sanchez Flores's side four points behind Saints and six adrift of safety...

Danny Ings, topless after flinging his shirt into the crowd, gives 'high tens' to the man he has perhaps helped keep in employment.

Saints move above Norwich into 18th place, just two points away from safety...

Southampton are over the line! Relief all around as the Saints - finally - celebrate a home win. Their first since 13 April...

My word! Watford's Adam Masina whips in a cross from the right, he's sliced it and Alex McCarthy is back-pedalling... he's tipped it over the bar.

Tense. Soooo tense.

Watford corner. Ben Foster gets the nod. The Hornets keeper almost scored against Chelsea the other week remember...

Jose Holebas's delivery is met by a Saints head to loud cheers. Almost there...

Ben Foster's heat map in the past five minutes would show he's been positioned on the halfway line.

Watford lump a free-kick, taken from just inside the Saints half, into the box but the home defence remain firm.

Now Saints have some defending to do...

A third would seal it... Sofiane Boufal drives into the left side of the Saints box, only to trip over himself as he looks to deliver.

Here comes the fourth official with the electronic board... six minutes of stoppage time. SIX!

Suddenly it is the Saints who have got bucketloads of belief. Watford's has drained.

Danny Ings charges forward as he tries to panic the away defence into an error. They just about clear their lines.

Ryan: Ward-Prowse is another kind, his free kicks are incredible. I remember seeing his first for England back for the U21’s in 2013 at Portman Road, he just gets better

Only Matt Le Tissier (seven) has scored more direct free-kick goals for Southampton in the Premier League than James Ward-Prowse (five)

While Ralph Hasenhuttl leaps off the ground with almost the same explosive power as Katarina Johnson-Thompson, his Watford counterpart Quique Sanchez Flores slides down his seat and just shakes his head in disbelief.

Watford had so much in control.

It has been coming, the first goal is a wonderful piece of skills from Djenepo to Danny Ings

And then this is what James Ward-Prowse it is all about: when it really matters he steps up.

Now they need to manage the rest of the game

Just a reminder of our entry after 50 minutes when Watford led...

Southampton have won just one of their last 43 Premier League games when trailing at half-time - drawing seven and losing 35, That was a 2-1 victory against Tottenham back in March.

And Watford have lost just one of their last 14 Premier League games when ahead at half-time - winning 11 and drawing two - a 2-1 defeat against Tottenham back in January.

Suddenly the Saints have belief. Pierre-Emile Hojbjerg drives forward on the left and is clumsily hauled down by Etienne Capoue on the edge of the box.

A free-kick 20 yards out and James Ward-Prowse is lining it up....

Relief all around St Mary's! Saints think they can win this now...
