Manchester City are furious with Manchester United boss Sir Alex Ferguson over his accusations at skipper Vincent Kompany.
Ferguson says Kompany deserved to see red for his lunge at Nani on Sunday.
The Daily Mail says Ferguson accused Kompany of having 'previous' when it comes to dangerous tackles. City refute this and are furious that the Scot should make what they believe to be a groundless comment about one of their key players.
