Knowing a win over already-relegated Southampton would all-but confirm a place in next season's Europa League, it looked like Roberto De Zerbi’s side would be frustrated. Kaoru Mitoma missed two golden chances and some sloppy play had some fans restless.
But Republic of Ireland striker Evan Ferguson, 18, put any nerves at rest with a powerful effort which Alex McCarthy couldn’t keep out just before the half hour mark. The youngster found the net again 11 minutes later with a composed finish after a superb run and cross by Mitoma.
The ‘We’re all going on a European tour’ chant was in full swing amongst the crowd at this point.
However, things took a turn when Mohamed Elyounoussi scored with a header at the near post from a corner after an hour. Suddenly, Southampton had Brighton panicking and the hosts were all at sea.
It looked like disaster had struck when Theo Walcott burst clear of the defence and chipped the ball over Jason Steele – but VAR came to the rescue and ruled out the goal for offside. The moment was cheered like a goal among the home fans.
De Zerbi responded by bringing on Danny Welbeck for Ferguson and Brighton were straight back on the front – with Pascal Gross restoring the two-goal cushion with a superb finish into the bottom corner.
Brighton had chances to add to their lead but the 3-1 proved to be enough, sparking jubilant celebrations at the Amex.
9. Julio Enciso - 5
Saw a lot of the ball in the first-half but struggled to make an impact. Didn't find it easy up against Kyle Walker-Peters. Did a lot of theatrical rolling around after fouls by the opposition. Replaced at half-time by Facundo Buonanotte. Unclear if it was a tactical change or if the youngster picked up an injury. Photo: Mike Hewitt/Getty Images
10. Alexis Mac Allister - 7
The World Cup winner’s unselfish pass led to the opening goal. Some slick passing when Brighton were in control of the game. The midfielder came inches away from scoring with superb volley just over the bar. Photo: Mike Hewitt / Getty Images
11. Kaoru Mitoma - 7
Somehow didn’t score in the first-half. Should have tested the keeper with a curling effort just inside the box. The Japan star somehow didn't find the net when a huge mistake at the back presented a seemingly simple finish but he was denied by the post. Redeemed himself with sensational assist for Ferguson's second. Shot found the side-netting just before half-time. Faded in the second half was replaced late on.

12. Evan Ferguson - 8
What a player this man is. Restored to the team and back amongst the goals. Powerful effort too much for the keeper. Keeper had no chance of saving second goal - composed finish. Replaced by Danny Welbeck after Southampton’s offside goal. Photo: Richard Heathcote/Getty Images
