Manchester United boss Sir Alex Ferguson has hit out at critics of the quality of his team.
Ferguson remains confident that United's record at Old Trafford - where they have dropped just two points in 17 Premier League matches this term - will see them through.
Fergie said: "I can't actually give all the reasons but our away record has been ordinary.
"The realisation of that away record has made us really step up to the mark at home because some of the performances have been very good.
"The criticism still was that we've not been great this season but we've scored more goals than anyone. We must be doing something right.
"Our home record is probably the best in Europe. It has to be on Sunday as it's a big game.
"Everyone is aware of the magnitude of this game. If we win we should win the league - but we won't be going for a draw."
