While the 34-year-old veteran is thanking her lucky stars for this incredible chance, she won't be happy just by showing up.
McManamon is there to prove she belongs on the grand stage and win it all.
"I’m not here to just participate. That's not what we're here for," the challenger told the Bangkok Post.
"But I'm very aware of who she is, what she's capable of, and [I have] so much respect for her, who she is as a person, as a fighter but it's all business in the ring, and I'm gonna bring my absolute best and I want her to bring her best too. And I want to find out who is the best because I want to challenge myself, really."
