Obviously in the post fight interview it took everything he could muster not to somehow work in a call out to Brock, but he wasn't so restrained in the post fight press conference.
When they asked him who he'd like to face, he said "Well I'd like to step in for Alistair and face Brock" even though it was sort of a total non sequitir.
Brock is the ghost who haunts his dreams. I doubt Brock ever gives him another shot because I don't see him sticking around much longer so Mir needs to move on.
