Manchester United won the FA Youth Cup for a record 11th time in front of the biggest crowd in the competition's 70-year history.
The 67,492 at Old Trafford for the 3-1 triumph over Nottingham Forest was almost 30,000 more than the previous best, at Arsenal in 2007.
Former United boss Sir Alex Ferguson was in the stands, along with current United first-team players Bruno Fernandes, David de Gea and Harry Maguire, to see Alejandro Garnacho score a decisive double in the final 13 minutes.
Garnacho, called up to the senior Argentina squad in March, kept his cool to send Aaron Bott the wrong way from a controversial penalty, awarded despite the forward being brought down outside the area by Zach Abbott following the Forest defender's miscontrol. After Garnacho scored, he marked the goal with a Cristiano Ronaldo-style celebration by shouting 'siuuu' - a drawn-out version of the Portuguese word for 'yes'.
Garnacho then sealed a record 11th triumph in the competition for United in stoppage time when he darted into the box, then benefited from a massive deflection as the ball flew into the corner.
Unlucky to fall behind after Bott failed to hold Rhys Bennett's downward header, the visitors, coached by former United reserve team boss Warren Joyce, fully deserved their equaliser, even though Josh Powell's speculative shot only went in thanks to a huge error from United's Czech keeper Radek Vitek.
"That boy could stand up in any stadium in the world and put a penalty away like that," said United Under-18s coach Travis Binnion regarding Garnacho. "What a future he has – and all his teammates out there, for that matter."
