34. Valentina Shevchenko vs. Priscila Cachoeira
Valentina Shevchenko is one of the most fearsome female fighters ever. Her technical ability is astounding as she brutally dissects her opponents. Brazil’s Priscila Cachoeira discovered this the hard way when she was on the wrong end of a brutal beating from the champion (via Sportskeeda).

However, her coaches failed her because they should have thrown in the towel. It became clear that she had no chance of defeating Shevchenko and the referee stopped the fight late. Shevchenko outstruck her 95-2 in a harrowing one-sided beatdown. Cachoeira was tough but this took years off her career and it could have been prevented by her corner.
