Bundesliga is weaker than La Liga.
Even if it was, which it isn't, they're on the same level with Atletico probably going mediocre again this season and no other team really having a major shot at staying within 20 points behind 2nd place.. You do need to consider the fact that Carvajal was chosen one of the best fullbacks (THE best?) in that league playing a full year. Montoya played 1000 minutes all year behind Alves. U-21 lineup selections don't really make a point in this discussion. Coaches play who they prefer to play and who fits best in their mind. Otherwise Llorente would have played a game at Euro.
There isn't a lot of arguments in favor of Montoya > Carvajal. And being Polish I have to say it didn't make any favors for Montoya to get toyed by Lechia forward Grzelczak (who is honestly a bit of a joke subject for people who follow the Polish league) for that goal while Carvajal held his own against PSG
