The 32 year-old, who had originally hopes to lure the veteran WBC title holder into a fight in 2013, could now battle compatriot Tyson Fury in the autumn, with the victor then potentially taking on Vitali in what could be his final fight in early 2014.
“Hopefully (Vitali happens as) that’s the goal, to regain the championship,” Haye told Sky Sports.
“Vitali Klitschko has to fight with a guy (Bermane Stiverne), I forget what his name is. He has to fight with a guy who just won a fight against Chris Arreola a few weeks back.
“If it does happen (with Vitali), it probably won’t happen until next year – so I’m just going to stay active as much as I can without getting injured.
“I’m looking forward getting back into the mix of things.”
Haye was due to return to the ring against former Vitali opponent Manuel Charr this summer, although injury ruled the Briton out of the contest and there are some doubts as to whether the fight will now be rescheduled after Fury pulled out of his touted clash with Kubrat Pulev.
