arreola i just dont like his style...to brawly and un mannered...not saying you have to fight like sugar...but you have to have a bit of polish. vitali is a tall rangy hard puncher... i think arreola will get decimated. wont get past the jab and a ritgh cross finishes it.
If you put 4 burgers in 4 ring corners and tell Arreola you will eat them if you beat Vitaly, I am sure he will kick Vitaly Arse for those burgers.
