EU is vacant now, Helenius-Rill will be for vacant title, easy win for Helenius. Like the idea of Cunningham & Arreola whoever mentioned that, honestly wouldn't mind the Chisora fight but the two mentioned above would be better names especially for PPV.
400k people just paid £17 to watch Joshua v Whyte + Eubank Jr in a eliminator. Whyte had zero name recognition in the UK before that fight. Joshua v Chisora with a decent undercard would easily be PPV in the UK.. Joshua is already the draw anyway and Chisora still has a name over here, he looks in good shape right now and has been in there with 3 world champs and although he didnt come close never really embarassed himself either - apart from getting blown out by Haye I suppose. If Joshua KOs Chisora it would easily be the most impressive thing he has done as a pro and I think Chisora would be a good test for him at this stage. Del Boy would def give him a few more problems than Dylan Whyte, who was punch drunk after the first couple of rounds.. legs all over the place..
He should do what it takes with the governing bodies to become a mandatory for one of their straps. Chisora and Price are washed up and would not add any value. He needs names that would boost his ranking.
