Kelvin Gastelum on Learning from Chael Sonnen

When Kelvin Gastelum is asked 22 minutes into this clip, what the most useful thing he learned from Chael Sonnen was, he replies:

He tells me that for a fight you can't worry about the outcome, you just have to worry about performing and that's what I'm thinking coming into every thing. I'm not thinking I'm going to win, just thinking about performing and doing what I need to do to get the job done.
