Ralph Hasenhuttl's men then found the equaliser just before the half-time whistle with Ward-Prowse making up for his earlier error to pick out Jannik Vestergaard, who headed home the corner.

Then, with 10 minutes remaining, substitute Danny Ings fired home on his return from injury after Southampton were awarded a controversial penalty, with Brighton players claiming the foul took place outside the area.

In the early exchanges the supporters looked to give their side an immediate boost, with Brighton starting on the front foot, and forcing McCarthy off his line to gather on two occasions.

Brighton had to wait until the 25th minute to take the lead when referee David Coote pointed to the spot after a Danny Welbeck cross hit the raised arms of Ward-Prowse.

Gross fired in the penalty after sending McCarthy the wrong way to put the Seagulls a goal ahead.

The home side looked to get forward at every opportunity while Southampton struggled to get going, despite their recent quick starts against Manchester United, Newcastle and Aston Villa.

Against the run of play, Saints struck the equaliser just before the break. Ward-Prowse continued his impressive record from set-pieces, crossing the ball from a corner for Vestergaard to head past Mat Ryan.

At the start of the second half, Tariq Lamptey looked to get forward down the right before playing the ball back to Gross who fired over the bar.

It was the first time the Brighton supporters will have seen Lamptey in person following his move in January from Chelsea, with his debut coming on June 23 against Leicester.

In the 79th minute, Kyle Walker-Peters was brought down by Solly March, with the referee initially awarding a free-kick before a lengthy VAR intervention changed the decision to a penalty.

Ings struck the spot-kick into the net on his return from injury, his seventh goal of the season, and his side held on for the victory.
