It is indeed a close fight but the result says it. Canelo wins the fight but it was too close, IMO.
I had expected GGG to come out a little more aggressively since I believe he was also aware that if it was a decision, he wasn't going to win. However, it is likely that he wanted to fight the way he does best. I believe that he is still capable of fighting and I think that he can continue to do so. It should not be viewed as a career-ending decision for him since he is already on track to become a legend. It is my belief that he will still be able to continue fighting for at least two more years, if not more.
^ Golovkin is obviously still capable of fighting. But the problem is we have seen his age taking a toll on his body. And because he is already 40 years old it is actually not recommended for him to continue his boxing career at all from now on. Especially if he wants to avoid any serious injuries. But I think at the end of the day everyone needs money and Golovkin is no different from that. So, I think he can take one or two easy fights going forward.
For Canelo, he should be looking to perform better from now on because he got a win to put him on the right track again. His next fight is going to be really challenging, so he should be concentrating really hard on that one against Bivol.
