LONDON — Molly McCann isn't one to call anyone, but she had a name after UFC Fight Night 208.

McCann (13-4 MMA, 6-3 UFC) scored another knockout with her elbows, using a spinning attack to create a flurry that knocked out Hannah Goldie in the first round at the O2 in London.

The win marked McCann's third in a row, and "The Meatball" now looks to test herself against the UFC flyweight champion's sister, Antonina Shevchenko (10-4 MMA, 4-4 UFC).

So I never call anybody out,” McCann told MMA Junkie at the post-fight press conference. “It's not for me to do. But when you talk about legacy, prestige, respect, who's the best in the game - and it's Valentina (Shevchenko).

Am I ready Valentina? no Am I ready Antonina? Let's see. I believe I am. It's not like a diss. It's not like, 'I think I'll 'f' you all over.

No not this. But I honestly think it's an amazing fight, and if they do a fight camp for me, if I ever get to Shevchenko, they'll have the blueprint.

But I'll also have the blueprint because I'll know how to beat his sister. So with the utmost respect, I mention his name because I think he is the best.

So I want you to tell him that I believe he's the best, so I'm trying to challenge him.

Shevchenko is coming off a split decision win over Courtney Casey at UFC on ESPN 39 in July. The win snapped his two-fight losing skid.
