Sounds like he's really reaching there. Khabib has always been super submissive to his father, and to his God, and his coach too, the only 'arrogance' you could point to is him standing with his opponents when his coach wants him to wrestle.
This will probably get brought up in the press conference, I wonder how Khabib will respond, Gaethje kind of starting to ask for the smesh.
I don't know who he spars with, but from watching some corner audio, his guys don't seem to be licking his ass or anything, they tell him pretty straight what he needs to be doing and if he needs to improve.
