George Groves is optimistic he will be fit for the World Boxing Super Series final but said it is "impossible to know" if he will have recovered from a shoulder injury for the showdown on June 2.
Groves retained his WBA super middleweight title with a unanimous points victory over Chris Eubank Jr in a bloody battle at a raucous Manchester Arena on Saturday.
The Londoner appeared to dislocate his shoulder in a frantic final round and went straight to hospital after setting up a decider against Callum Smith or Juergen Braehmer.
There was a lot of trash talk in the pre-fight build to last Saturday's fight.
Groves believes Eubank Jr. will never know what his true potential is - because he has no real trainer and feels that he can do everything himself with using the simple corner advice of his father, former world champion Chris Eubank Sr.
Groves knew exactly what to do in the contest from watching several of Eubank's recent fights - because he rarely ever changed his fight tactics from contest to contest.
The champion offered some harsh words of reality for Eubank.
"He dreams big, which is good on him, but tried to fill it out with fairy dust," Groves exclusively told Sky Sports.
"There is no substance to anything behind him. Maybe this is the best way to do it, because you'll never really know his limitations, but he's never going to go any further. He either should try something else, or perform."
"For this last fight, everyone has talked about the gameplan. I don't think it's so much the game-plan that was that important, because we knew what Eubank was from fighting, particularly simple and so the gameplan was straightforward.
"There was nothing elaborate about it. He was saying 'just step around to your right, breathe out, take a walk, he can't adjust his feet. Keep pumping the jab in his face, bring this shot in, bring that shot in'. That was all we did for the night. We didn't really speak of a specific gameplan before. It was just don't have his fight, have your fight, and away we go."
