And the next generation of Saints stars are following the club captain's example, as one Under-9 player has shown in spectacular style with a stunning free-kick of his own.
There were also some spectacular goals across our Under-23 competitions over the weekend.
On Friday, Nohan Kenneh and Max Dean scored brilliant goals in Leeds United's 2-1 Premier League Cup win at Wigan Athletic.
Leeds were at it again in Premier League 2 Division 1 three days later, with Amari Miller curling a superb shot into the top-left corner in a 2-0 victory over Derby County.
Alves, a 16-year-old forward, swept the ball beautifully into the bottom-right corner for his first PL2 goal.
Then with three minutes remaining, Marcal-Madivadua thundered in a powerful late winner that took the Foxes up to 10th in Division 1.
