Oda said that in Wano he will have to understand that to win sometimes you have to sacrifice something (something like this at least) I hope he stays true to his words since imo he needs another Sabaody. His worst loss post time skip was vs Kaido which resulted in him getting a teacher who made him stronger with new skills and a plethora of new allies in no time so that actually was no loss but a big gain. What is left was a triumph march (see beating Kata and learning FS mid fight despite being way weaker). So he needs to lose, maybe we will get just when the flashback ends.
