Arsenal 1-2 Man Utd: It wasn’t all about the substitution

Arsenal 1 (Van Persie 71) Man United 2 (Valencia 45, Welbeck 81)
(Premiership)

The bare facts make for grim reading. Defeat to United leaves us fifteen points behind them, and eighteen off the pace set by their city rivals. Our own neighbours remain ten points above us despite their loss earlier in the day, and that critical fourth spot is still an elusive five points away.
