Come on. Probably even more comfortably behind second
Not at all if you're talking about domestic performance. In fact, you could argue it's pretty tight as to what the order of the top three should be. Since World War II when Arsenal bribed their way into the top flight:
Man United: 18 league titles, 11 FA Cups
Liverpool: 16 league titles, 7 FA Cups
Arsenal: 13 league titles, 13 FA Cups
Everton: 7 league titles, 4 FA Cups
Chelsea: 6 league titles, 8 FA Cups
Man City: 6 league titles, 5 FA Cups
Liverpool's European Cups obviously put them way ahead overall, but the European Cup didn't even exist during Arsenal's most dominant period where they won more than half of those titles.
Edit: Arsenal also have the shortest gap between winning league titles of any club in that period. 18 years. Sadly that figure is about to start getting bigger.
