They're calling that championships but take Oleksandr Zelenskyi there for example.... he only has 9 amateur fights and 25 rounds in total. His other opponent has an amateur record of 8 and 4. I don't consider that world level.
Jalolov didn't have Joe Joyce's number. Itauma would make him look stupid. Jalolov is only interested in going back to the amateurs and knocking out 21-year-olds; he's not a serious pro, unfortunately. If he were, he might push Itauma at some stage, but I can't see it, he's not going to get any better, whereas Itauma is still a few years from his prime.
