Manchester United's young team are into the quarterfinals of the 2007 Champions Youth Cup in Malaysia.
Febian Brandy's spectacular lob - one of the goals of the tournament so far - was the only goal of the Reds' opening encounter with the Portuguese side, and the diminutive striker was on target again against Boca.
Brandy hit the clinching goal in a 3-2 win over the Argentines, with earlier goals coming from Sam Hewson and Daniel Drinkwater in a thrilling triumph for McClair's side.
United will face either Barcelona or Juventus in tomorrow's quarterfinal.
