Yeah his cl success is weak for a coach of his level, was also often unlucky but with Bayern and City he should have won at least 2-3 cls
His Barca career + Pl domination have been insane though, probably greatest league coach ever
Yes, could have done better in CL, but he was really unlucky in seasons where he should and could have won it.
In particular:
11/12 Barca totally annihilated that Chelsea and somehow got eliminated. No one doubts that we would have won it in that final against that Bayern
15/16 Bayern best team in Europe, should have won it, got unluckily out by Pathetico in that SF
18/19 City got out by Spurs in totally undeserving and unlucky fashion
21/22 City totally dominated Madrid in that 2nd leg, Madrid did not have a single chance before that voodoo 2 min spell in injury time
Just look at these 4 cases, not even talking about seasons they deserved to go out (e.g, Lyon, Monaco, this season, Bayern Madrid SF, etc.)
Being so unlucky in crucial CL games, and his CL tally is only 1 in 13 years, but could have been 5 in 13 and that changes the perspective
PS: Same for KLopp. Lost that 2022 final totally undeservingly. 2018 final was balanced, no team dominated, but Ramos and Karius did him dirty.
3 Cls instead of 1 changes the perspective as well
