Today is one of those days. City, of course, can lose at Arsenal, or draw, and United will likely win a far easier match against Newcastle at Old Trafford. Pep vs Mikel, master vs understudy. Piers Morgan, too. Thus today is as big a soccerday as we can have under the circumstances. However, today will not change the shape of the race for City will win and United will win and the gap will remain ten with thirteen matches left.
