Hamed's only foray into the Premier league was against Barrera and we all saw what happened there, Marquez is in the Premier league and he wins.
I've said it before and i will say it again Hamed was the 'Prince' who turned back into a toad. Barrera went on to fight Morales and Pacquiao twice each and Marquez too yet Hamed seeks no rematch with Barrera?
He loses one fight, then waits another year then retires age 28? (Barrera was the same age as Hamed when they fought) Real champions comeback from defeat, they learn and live to fight another day and overcome setbacks. Marquez is the perfect example.

Marquez, Pacquiao and Morales all beat Hamed.
