Only two outcomes await Arsenal from their position atop the Premier League table: agony or ecstasy. The club's supporters lurch helplessly between the two extremes, contemplating the glory of a first title since 2003-04's "Invincibles" and the ignominy of losing the eight-point lead they will hold on April 1.
This roller coaster of emotions renders all remaining games a health hazard, each setback delivering a sense of foreboding that a fine season could suddenly collapse, while every positive moment is fresh affirmation that this really is going to be their year.
