I don't think any blue is likely to be distracted by bogus measures, like back to back league wins, the invention of which is only to attempt to diminish the greatest achievement in English football.
No-one is claiming the title of the greatest "club" of all time, simply the greatest "team" of all time. I haven't checked but I'd bet my bottom dollar that none of the clubs who retained the title did so using the exact same squad as the previous season.
By any real metric you care to mention, this squad of players and management has been the greatest team in the history of English football. That cannot be disputed with any degree of credibility and I'm going to relish this season for the rest of my life.
