Don’t think United was the same team in 2010 that they were in 2007. To think that they still managed to win a couple of leagues more and lost once on a single point and once on goal diff says a lot.
Yes, it was the winning mentality instilled by Ferguson - the league was also on its way down at that stage, essentially following the departure of Ronaldo, Alonso and Mascherano to Spain - of course new talent had come in (Aguero, Silva etc) but were yet to truly establish themselves. Chelsea had their first and last hurrah (at least on a European scale), Arsenal were rapidly declining, and we wouldnt be relevant again for years till Klopp showed up (save for Luis Suarez).
But his point was that it wasn’t just because of Barcelona...the two years you made the final, it happened to be against Barca. What about the other years?
It’s not as if the Chelsea win had you dominating them in the final either.
More just a point that it was probably the best United side of all time, and definitely the one that performed the best on the European stage consistently, but it didn’t “dominate” Europe
I do rate that United side highly though - prior to this Liverpool one, had it as the best team in the last 30 years in England.
