I'm a bit skeptical of Canelo at first, but after this fight I'm convinced that he is just a tough mofo. Plant's physique looks intimidating, but Canelo keeps applying pressure, and moves forward. Iron chin, fantastic footwork, and powerful punches. It seems that no one can beat Canelo in the Middleweight division. However, I don't think he will move up to light heavyweight, but let's see. I'd like to see him defending his title over and over again.
I also don't see that possibilities, it's much better to him to keep fighting and defending his title on his weight,
No need to step up and make yourself uncomfortable, for sure their are many challengers that will ask to fight him and try to take his thrown.
More fight means mire money for him,
Let him enjoy his victory and wait if whatever plans he have for his career, future will be revealed in the right time.
Canelo added more to his fame, he deserve everything after seeing how he brings this fight to an end.
