Records have to be taken within the context of the league. City & Liverpool are racking up huge points & win totals due to the diminishing quality of the league. Utd have been in a state of continual transition. Arsenal went stagnant under Wenger & are getting worse. The bottom half teams of the league have also been very poor for a few years.
There is no denying City & Liverpool have good teams ATM. To put them in conversations as the best PL teams ever is ludicrous. It's very easy to do what they have done as the league isn't the challenge it was years ago. SAF won 3 PL in a row twice but never got close to the records that City set in 17/18. It's looking likely that Liverpool will take City's records this season. This all indicates the league is weak.
You had four teams in European finals last year, the eventual champion not among them, and you say the league is weak? IMO, this is the strongest EPL I've seen and I'm watching football since 2001.
Sorry, I know Ferguson has a godlike status in here and rightly so but as impressive as his consistency, longevity and constant reinvention is, his peak teams were not on the same level as these two, IMO. Both Pep's City and Klopp's Liverpool are better than SAF's best teams.
