I’d say so. We put our Wilf Wild and Joe Mercer years down as our great eras pre-takeover and they won one league title each.
Klopp has won one of every trophy other than the Europa League (and got to the final in that) and two other losing CL finals in his time at Liverpool. I think that’s a very good achievement and a good trophy haul while a team as good as City under Pep have been around.
They’ve also won things we haven’t managed to yet in that group of trophies.
I don’t think we should go down the road of our neighbours in belittling what other clubs achieve (I used to think United fans were terrible for that when they were at their peak Ferguson best) because it diminishes our own achievements when it’s in an era when we’re also winning stuff as it suggests the teams we’re winning over are nothing special so our achievements aren’t that great, plus it finishes our historical stature when Klopp’s seven trophies is only three short of our trophy count in our first 117 years.
