Canelo fears GGG beacause he knows he has no chance. Canelo will hold on to hisbtitle for as long as he can before he vacates to avoid GGG. Known my truth
GGG will be 10x bigger than Canelo once one of these chickens actually step in the ring with him. GGG is the PPV king, he just needs one big name to man up.
They both had full countries behind so I'd say that had a lot to do with it. With GGG, not so much. Which sucks for him but still strongly believe Canelo has no chance for a victory no matter how big his fan base is.
