He had his hand up to his face, happens all the time, all the time. He wasn't pushing it against his face or anything, well not until Mike started getting pissy and pushing his hand away. Fighters always put their hands up.
I love the way some people find literally anything to get annoyed about with Bisping
Vitor had his hand right in his face. Not just up, right in his face. He knocked it away, far play. Kinda like when Cain imitated JDS and stuck his right in his face 'cause he knew JDS was gunna do it to him. This was Mike's way of not taking it like a bitch
