Patrick Vieira attacks Manchester United over referees

Patrick Vieira has claimed referees are giving Manchester United a helping hand in the Barclays Premier League title race, sparking an angry response from Rio Ferdinand. Manchester City ambassador Vieira, asked in a BBC interview about Michael Oliver's failure to award a late penalty to Fulham at Old Trafford on Monday, said: 'When United play at home they get some advantage that other teams don't get. When you go to United, Madrid, Barcelona or Milan, it's always difficult for the referee to go against these kind of teams.
