This is the fundamental problem. If you start out with a view that perfection is mandatory then any missed chance will seem annoying. If you on the other hand begin with a view that all players occasionally miss chances and all keepers occasionally stop shots they may ordinarily not save, then you begin to see things in a more nuanced context. Zlatan has scored something like 57 goals in his last 60 fixtures going back to last year and the first two months here, so you'll forgive me for not participating in any negative hysteria if he misses a chance or two. I'm more interested in a longer, more protracted view of where we are going as a squad and a club than to throw my toys out during a sluggish stretch of fixtures.
