Alvarez v Golovkin II
Some 364 days ago they drew - it was the topic of widespread controversy.
Then Saul 'Canelo' Alvarez failed two drugs tests - bringing more controversy.

No more room for nonsense or talk now. You ready?
Alvarez v Golovkin II
One man schooled, brought through the amateur system, polished.
One man fighting professionally from the age of 15 to escape financial hardship.
Two men with varying paths to the top and when they got there, ran into one another in controversial fashion. Their shared story will no doubt go on to be the focal point of books, documentaries and history.
This morning they write another chapter.
