I suppose if winning things is the main criteria, then it has to be between Liverpool and Man City. As for European places, I think there were no great surprises there, so not sure if you could include any of those as having a 'best' season.
Who would have thought there would be a time when the mighty Man U don't even get a mention? :lolol:
As to the question, I'd put us up there with the best, for overall achievement. :)
