No need to marinate... Kova is tied up with Yarde Zurdo probably needs another 175 fight before a title shot Need to make it happen...
I rather see Beterbiev vs Kova, when he's done with Yarde. But a Gvozdyk fight would definitely be cool as well.
I think Beterbiev would probably want to find Kovalev first. But, if Kovalev loses his title or is unavailable (with some other bigger fight, for example) a fight vs. Gvozdyk is possible. But not in the summer — later, I think, by the end of the year.
