COACHING AIN'T EASY TMZSports.com
"The Ultimate Fighter" coaches Alexa Grasso and Valentina Shevchenko will fight at the culmination of the hit show -- and the flyweight champ has a venue in mind -- The Sphere!
TMZ Sports talked to 30-year-old Grasso -- who will debut as coach opposite rival Shevchenko on TUF 32 on Tuesday night -- where we asked the 125-pound title holder about the show and eventual trilogy fight with Valentina.
It's no secret the two female stars are fighting ... but the question is when and where.
