UFC 289 -- How Irene Aldana can pull off the upset vs. Amanda Nunes - ESPN

Irene Aldana will look to add to what's already been an excellent year for Mexican-born fighters at UFC 289 on Saturday (10 p.m. ET on ESPN+ PPV) when she faces defending two-division champion Amanda Nunes in her first shot at the women's bantamweight title.

Aldana, coming off a third-round knockout against Macy Chiasson at UFC 279, looks to bring Mexico its fourth UFC title since January, and second women's title during that span.

Former UFC women's featherweight and current ESPN MMA analyst Megan Anderson breaks down how Aldana might be able to pull off an upset and continue Mexico's dominant run.

After coming up short against former women's bantamweight champion Holly Holm in her first UFC main event in 2020, Aldana earned back-to-back stoppage wins over Yana Santos and Chiasson. Aldana was then set to take on Raquel Pennington in a No. 1 contender bout — a rematch of their 2019 fight, which Aldana lost via split decision. Nunes was scheduled to fight Julianna Peña in a rubber match, but Peña withdrew due to an undisclosed reason. Aldana seized the opportunity and agreed to fight Nunes on short notice.
