Manchester United manager Alex Ferguson accused Chelsea's Brazilian defender, David Luiz, of acting like a "dying swan" in the incident that led to United defender Rafael da Silva being sent off in their encounter at Old Trafford.

United lost 1-0 to its London rival on Sunday, a result that means Chelsea can effectively secure a top-four finish and Champions League soccer if it beats Tottenham Hotspur at home on Wednesday.

The veteran United manager conceded his team did not deserve anything out of a game in which it failed to score at home in the league for the first time in 67 matches, but he was angered by Rafael's late dismissal.
