Carlo Ancelotti has refused to condemn Sir Alex Ferguson's outburst towards referee Martin Atkinson after Chelsea's controversial Barclays Premier League victory over Manchester United. Ferguson has denied a charged of improper conduct by the Football Association for his outspoken post-match attack on Atkinson following United's 2-1 defeat at Stamford Bridge on Tuesday. Chelsea boss Ancelotti has described Ferguson's reaction as "normal", saying: "After the game, you have emotion about the game so, sometimes, you speak about decisions. This is normal, I think."
