Rio Ferdinand admitted he was "embarrassed" after seeing Ronaldo applauded off the pitch by Manchester United fans after his legendary hat-trick in the 2003 Champions League.
Los Blancos travelled to Old Trafford for the second leg of the quarter-final tie, carrying a 3-1 lead from the opening fixture. And the LaLiga side blew United away courtesy of a stunning performance from Brazilian striker Ronaldo.
He opened the scoring after just 12 minutes, firing into the near post after Guti had carved up the United defence. Though Ruud van Nistelrooy got United on level terms, Ronaldo continued his impervious form to take the tie away from the Red Devils.
