Legend Vasiliy Lomachenko on top of the world again after beating George Kambosos in Perth

Ukrainian boxing legend Vasiliy Lomachenko became a two-time lightweight world champion and opened the door to some major fights after producing a vintage performance to stop Australia's George Kambosos Jr in the 11th round in Perth on Sunday.

The victory immediately sparked talk of a potential showdown with Americans Gervonta 'Tank' Davis or Shakur Stevenson. It's also possible Lomachenko faces the winner of next week's WBO lightweight title fight in San Diego between Emanuel Navarrete and Denys Berinchyk.

"I'm again world champion. I want to come back home and spend time with my family," said the 36-year-old Lomachenko when asked about his future.

"We trained hard for this moment. My plan was to adjust to my opponent. This is what I did during the fight and the end of the rounds I need to finish strong.

Kambosos, a former champion himself after a signature win over Teofimo Lopez in 2021, saw his
