IBF welterweight champion Errol Spence feels confident that WBA super featherweight champion Gervonta Davis (20-0, 19 KOs) would defeat Vasiliy Lomachenko (11-1, 9 KOs), who holds the WBA lightweight title.

The two boxers were competing at the same weight - until two weeks ago, when Lomachenko moved up to 135 and recovered from a sixth round knockdown to secure a tenth round stoppage of Jorge Linares at Madison Square Garden in New York City.

Davis became a two-time champion at 130 last month, when he blew away Jesus Cuellar in three rounds to capture the WBA belt.

When sizing the two boxers up - Spence can only view one man as the winner.

"Tank Davis would beat him. He would smoke him. Tank Davis can fight. He's quick, he's fast, good feet, good eyes, he can punch with both hands. And I think that he's way stronger than Linares, he's quicker than Linares," Spence told Fighthype.com.

Some would argue that Lomachenko, in twelve fights, has faced better opponents than Davis - which Spence says is irrelevant to the overall outcome.

"It don't matter about resume, it matters about skills. You can look at my resume and then look at other people's resumes. I have a resume, but some people have better resumes... it don't mean they are better than me. Tank has the talent and the skills to beat Lomachenko," Spence said.

Davis' promoter, former five division world champion Floyd Mayweather, had recently reached out to Top Rank, who handle Lomachenko, to match their two boxers in the near future.

Davis would have to move up to the lightweight division to take that fight - but Spence cautions that the 23-year-old fighter would actually be more dangerous and stronger at the higher weight.

"I think Tank would do better at 135, as he sucks down to get to 130. I think he'll be way stronger at 135 than at 130," Spence said.
