I guarantee you that Klopp admits he's behind Pep. He'd be absolutely delusional if he believed anything else. Klopp is brilliant, likely the second best manager since SAF, bit there's no way a manager that won 3 leagues and one UCL could ever be better than someone who won 12 leagues and 3 UCLs.
Pep has the better trophy haul,but he should have given the players that he had at barca,the fact that he was at munich,so winning the league with them is always fully expected,and then he went to a cheating club that easily outspent everybody.It would be absurd to not to expect a much bigger list of honours won.
Put aside pep winning titles and 2 ucl trophies at barca because 1)if he had that side(which is seen as probably the best side ever,including the best ever player in his prime)but didnot win those trophies he would have greatly underachieved 2)klopp was building up a team with dortmund so winning titles while up against bayern is massively overachieving.3)barca paying refs during those seasons.
Pep has won more partly because he had many seasons with a great barca side,so that is about 18 seasons at clubs with amazing squads.
So lets compare klopp at dortmund to pep at bayern...both won the bundesliga,but klopp got to a ucl final,despite losing some of his star players to bayern,who they faced.Pep underachieved at bayern,i guess he either needs messi or managing a cheating oil club aka easy mode.
Then at man city,he never underachieved but he never overachieved either, because with the team he inherited, and man citys spending power compared to lfc(who had to sell star players to bring in big signings)there was no season where pep shouldnot win the league.His number of ucl wins at man city is underwhelming,and klopp reached more ucl finals during that time.Klopp also inherited a very poor lfc squad.
Pep has never overachieved,but klopp did multiple times.
Then there is the cheating,where klopp fully deserved 3 prem titles instead of 1.
So from around 2010 to 2024(klopps seasons with great players) klopp won:2 bundesliga titles,3 prem titles and the ucl.While reaching 4 ucl finals.
Pep won:the bundesliga.Pep cheated his way to :6 prem titles and a ucl,reaching 2 ucl finals.
Conclusion:Take away the cheating and pep has won the bundesliga at bayern,thats it!Add the trophies gained through cheating and his resume looks amazing.
Klopp wins as much if not more with that barca side,he did better at dortmund than pep did at bayern,and klopp with man citys spending power would have won more than pep has.
So i agree that peps credentials on paper seem far better,that is obvious,but to believe that he is better than klopp you need: 1)To turn a blind eye to a huge amount of cheating. 2)pretend that klopps spending was anywhere near man citys.3)ignore the fact that pep inherited great sides so has had about 18 seasons managing great squads.Where as klopp only had about 9 seasons with a great squad(afew seasons at dortmund and 2018 -2024 at liverpool.)
He only had about 9 seasons where he had a great team(one of which was a write off because of a huge injury crisis aswell)yet he still (rightfully) won 5 titles and a ucl.
Compare klopp to Sir Alex:they both inherited mediocre squads,Sir Alex took 7 years to win the prem(with no oil clubs or cheats in the league)whereas Klopp won the prem and ucl within 5 years,and it would have been 3 prem titles and a ucl in his first 7 years if not for man city cheating.Ofcourse Sir Alex went on to win a huge number of trophies,mainly because of his highly impressive longevity.
