Another volcanicly, smokin' hot bikini model is obsessed with Cristiano Ronaldo ... and she wants TMZ Sports to help hook her up. 

So, here. 

You're looking at Tanya Mityushina -- a 24-year-old Russian-born model (34-24-34) who stripped down to a couple of well-placed strings for the 2016 Sports Illustrated Swimsuit Edition. 

She's also modeled for Victoria's Secret, GUESS and Bebe. Straight fire. 

Tanya knows Ronaldo has a girlfriend. Tanya also knows relationships don't always last forever. 

Tanya is taking her shot. 

Get it, Tanya.
