No offense for all Munguia fans, but right now is undisputed king of super middleweight and middleweight division. Munguia might be really good, but a miracle must happen for him to win by decision. Munguia can win only by a knockout. Even if he knockdown Canelo, I am sure that judges will give only 8-10 in that round and Canelo will still win by decision. The best Munguia can get in such scenario is a split lose. For Canelo to lose by decision, I think this is possible only if he goes to a different weight class.
Yes, a miracle for this fight applied to Munguia's case against Canelo, you need to win overwhelming if the fight is too close the champion keeps the title, as a challenger you need to take the title away from the champion.
For Munguia to win against Canelo he needs to overwhelm and dominate the fight, as much as possible and knock Canelo out, this is a gigantic task for Munguia he knows it but Canelo will not easily give in and Canelo has never been badly hurt in any of his fights, but miracle does happen and we have seen this happen in many fights.
I'm not going to miss this fight it's a battle of determination by a young challenger against the face of Mexican boxing, so it's going to be interesting and action-packed.
