Mourinho's Chelsea have the 15 goals against season.
Arsenal have the invincibles.
United 99/00 are the only English winners of the treble.
United 07-09 won it 3 times in a row.
City 17/18 have 100 points (and a dozen other records).
City 18/19 are the only team to win all 4 domestic trophies (and the only domestic treble).
Yeah of course Liverpool will remember their title forever, just like Blackburn fans or Leicester fans, or how City remember Mancini's title.
They simply will never be remembered by history as one of the best league sides ever, and that's what they threw away. Of course they don't care now, they'll care in 5 years, and 10 years, when people look back at the best sides the country has ever seen, and no one mentions them.
Duncan Alexander made this point really well on the totally football podcast today or yesterday. They won the league in December, they were going for something bigger - the quadruple, the treble, the CL+PL double, the points record...and failed over and over until all that was left was a normal, run of the mill title win.
They all admit they played much better football last year. They haven't scored many goals, they haven't had a great defence, they failed to break out winning streak record, they lost a bunch of games at the end.
In 10 years it is possible people will look back at this title and the reason it'll be remembered is because it was against Pep's City, like Mourinho's one win against Pep's 3 at Barca, which when you consider what their season could have been...
