Lomachenko produced a battling display to beat Britain's Luke Campbell on points and add the WBC lightweight title to his WBA and WBO belts.
"I said before it wouldn't be easy for me; he is smart, technical and he has a big reach," he said. "He has power and he gave me a couple of good shots but I wasn't hurt.
"I was close to the knockout but it doesn't matter about the result; we just win. I will watch it on TV and understand what happened in the fight, but if I am to score it out of 10, I will give it a seven."
