I'll be amazed if we don't fall victim to a dodgy refereeing decision that costs us this game. It's not good for the Premier League if one team runs away with the league and if we go 11 points clear after the derby it will be a huge task for anyone to catch us. The Premier League and Sky won't want that.
In terms of the match itself, Arsenal created a lot of chances against United. We're a better team than Arsenal, but we'll need to be at our ruthless best as they are good on the counter. If we play to our best they won't be able to cope with us.
