Vasiliy Lomachenko says he is "ready" to face undisputed lightweight champion Devin Haney after defeating Jamaine Ortiz on his return from military service in Ukraine.

Three-time lightweight champion Lomachenko returned to defend his homeland in Ukraine after the invasion by Russia, before resuming his career on Saturday with a unanimous decision victory over Ortiz.

The 34-year-old will now eye a clash with Haney, who was in attendance at Madison Square Garden in New York and outlined his hopes for fighting Lomachenko, stating "hopefully we can get it on".

"I will be ready," replied Lomachenko, who reportedly rejected a major title unification with George Kambosos earlier this year, instead opting to return to Ukraine and enlist for the Territorial Defence force.

Lomachenko added on his return against Ortiz: "I'm happy to be back in the ring and make this great show. He is a tough fighter, he is a good fighter."

As for the mouthwatering prospect of a clash between Lomachenko and Haney, the Ukrainian's promoter Bob Arum suggested a potential clash would be a meeting between the two best lightweights.

"The fight to make in the lightweight division is Haney versus Lomachenko," Arum said.

"We will do everything we can to make the undisputed championship showdown that all fight fans want to see. They are the world’s premier lightweights, and it would be a fantastic battle."

Two-time Olympic gold medallist Lomachenko is expected to return to Ukraine to help his home country.
