Sergey Kovalev says he is ready to unify the light-heavyweight division again.
'Krusher' returns to the ring on November 25, when he fights Vyacheslav Shabranskyy for the vacant WBO title, live on Sky Sports.
Kovalev held three of the four recognised titles before losing back-to-back fights with Andre Ward and told fighthype.com: "I want all the titles.
"For me every fight is important but right now this is the situation where I lost the belts, but thank God I am fighting for them again.
"It is a great opportunity to come back at this level and be a champion and prove I deserve it, with another unification fight.
"We should make interesting fights with all the guys, four titles and maybe in the future, we have one of those series."
Kovalev didn't rule out a showdown with Russian compatriot Dmitry Bivol.
Bivol won the vacant WBA World light-heavyweight strap - vacated by Badou Jack - in Monaco, two weeks ago, knocking Trent Broadhurst out in the first round.
Kovalev has seen the 26-year-old come up and left the door open, providing he takes care of Shabranskyy at Madison Square Garden, New York, before the end of the month.
"I knew this guy from the amatuers," he said.
"We went to the same Russian boxing gym but I cam on much earlier than him.
"He is tough and is talented and a good fighter and the WBA champion. Let's see what happens in the future."
The WBO was Kovalev's first world title success back in 2013, when he beat Britain's Nathan Cleverly.
He added the IBF and WBA Super versions by out-pointing Bernard Hopkins in 2014 but after three defences lost them all to the now-retired Ward.
The WBC light-heavyweight holder is still Adonis Stevenson, with another Russian, Artur Beterbiev, recently joining Bivol in the elite bracket, by claiming the vacant IBF.
Watch Sergey Kovalev vs Vyacheslav Shabranskyy, from Madison Square Garden, New York, in the early hours of Sunday, November 26, live on Sky Sports.
