They fought 2 of the p4p top 10 boxers in the world, Kell Brook's level previously was mandatorys and Shaun Porter, who has since gone on to lose to Thurman aswell. Yes he's a world champ but he is yet to prove himself a world class boxer. If he fights and beats Khan and Spence this year then I will class him as world class,
Kell is and has been one of my favourite fighters for many a year and I think he can go on to do great things, but to call him world class at this moment in time because he has demolished Jojo dan and Bizier wouldn't be right.
When the fight comes around Khan wont have fought at Welterweight for over 2 years, his wins previously haven't exactly screamed world class, Algieri, a keep busy fight for a lot of welterweights, Alexander, a natural lightweight who never did anything at welter Collazo who's never really troubled anyone at genuine world level.
Khan has never beaten anyone that has any power, he has now resorted to avoiding anyone with any power and see's Brook as his biggest and only real pay day.
