Let's continue

So I make that 10 seasons without a trophy since 1978 but, if you include "runners up" being a measure of success then that's 2 seasons since 1978 without success, because he twice finished 3rd in the premier league.
2 seasons without success in 35 years (where 3rd in the Premier league was seen as failure).
I don't see that ever being equalled.
In reality half the clubs in the Premiership view avoiding relegation as a measure of success, half of the rest see a top half position as success, half of the remainder would be happy with a top 6 finish, a couple would be ecstatic with 3rd place just once every 5 years and about 4 clubs view 3rd place as a failure (Actually make that 3 because Arsenal have, in my opinion, dropped out of that top 4..it's basically Man U, Man C and Chelsea now).
Anyway, nobody is ever going to get a 35 year run like that again.
Bob Paisley had an amazing 9 year run, Bill Shankley a longer but less trophy-dense 15 years (but, more importantly than Paisley I think, built the modern reputation of today's Liverpool).
Liverpool are now without a "League 1" (Premier League) trophy since 89/90, that's a quarter of a century approaching. It could soon be the case that no Liverpool squad member will have been alive the last time Liverpool were the top English team.
As someone who grew up watching football in the 70's and 80's that seems incredible.
Fergie said he wanted to "topple them from their perch" ...and he did just that.
