Just imagine how annoying it is to fight with blood on your eyes. The fighting style of Khabib requires that you must have both hands exerting pressure at all times during grappling. How is he going to perform if he gets a massive cut? I have been watching his old fights and it seems hes never had to deal with that feeling. Tony has blades for elbows, I don't believe Khabib's skin is somehow impossible to cut.
