Man City is lucky they played us without Timber and with Martinelli and Partey coming back from injury. Otherwise we would have beat them for the third time this season and we'd be four points clear.
Liverpool, West Ham, and Fulham are lucky they played us without Partey or Timber, or else we would have won those games and, along with the City result, we'd be 12 points clear.
Fulham is also lucky we played them before we integrated Raya. Otherwise we would have beat them, and now we're 14 points clear.
Spurs are lucky we played them without Martinelli. Timber, or Partey, and before Jorginho and Havertz found their role in the squad, or else we'd have beat them. 16 points clear.
Chelsea is lucky Mudryk mishit a cross, or else we would have beat them. 18 points clear.
Newcastle is lucky they played us without competent VAR, or else their goal wouldn't have stood and they'd have been a man down. Add in their luck that Partey, Timber, and Jesus weren't fit and that's another three points. 21 points clear.
In December, Aston Villa was lucky that Timber, Tomiyasu, ESR, and Partey all were not fit. Otherwise we would have beat them. 24 points clear.
Really, looking at it, Arsenal is pretty unlucky not to be 35-0-0. Unluckiest club?
