Brighton are having their best season in history, and if anyone needed proof of that, a nerve-wracking win against Manchester United is there for them to realize the great momentum Roberto De Zerbi's men are enjoying right now.

The game between the Seagulls and Manchester United seemed destined to end in a goalless draw, but a late penalty kick transformed by Alexis Mac Allister into a game-winning goal kicked off all celebrations at Falmer Stadium.

The home team had enjoyed at least two clear chances of taking the win in the final moments of the match, but a deflection by Bruno Fernandes and a save by David De Gea kept the Red Devils alive. Unfortunately for Ten Hag's crew, a blatant handball by Luke Shaw was spotted by VAR officers and handed the penalty right away to the home team.

The Seagulls also found another reason to celebrate their entrance in the league's record books, but something tells us Manchester United fans will not appreciate that.
