Manchester United led 1-0 on the night and 2-1 on aggregate when Nani raised his foot high and connected with Alvaro Arbeloa's ribs in the 56th minute.

Nani did not appear to see the Spaniard and had his eye on the ball throughout the incident, but he was sent off - prompting a furious Sir Alex Ferguson to head towards the touchline to remonstrate with the officials.

Real took control against the 10 men with two goals in quick succession from Luka Modric and Cristiano Ronaldo, and despite a late rally by the Premier League leaders, those strikes were enough to settle the tie.

Fifa law 12, fouls and misconduct, states: "A player is guilty of serious foul play if he uses excessive force or brutality against an opponent when challenging for the ball when it is in play."
