Khan is the new Wlad Klitchko. Punch punch lean, punch punch tie up. Dirty fighter

It's difficult not to tie up when your opponent comes at you head first with his head down by your gonads.

Yes Khan was pressing him down and holding but what else was he going to do? Collazo never stayed upright when he came inside.
