This was an incredible run, however you look at it.
This season, City have been touted as the best team ever seen in the Premier League. Of course this was largely when they looked like they were on their way to a quadruple winning, invincible, record points breaking season. Now here we are, with the only thing they're aiming for now being the points total. The league and the league cup is a decent haul, and very good if they break the points record, but it's not quite "best ever side" levels.
I'm pretty certain no other English side, at least in the Premier League/Champions League era, can boast such a run, and I'm not sure there are many across Europe's other top leagues who can boast a similar run of league dominance, while consistently reaching the late stages of the Champions League, as well as going deep in their domestic cups.
This doesn't even include a further league win in 12/13 either.
