I second that. I think that his trainer is just fine. If he does good against Lara he should keep him.
Why does he need a new trainer? Canelo is a boxer/puncher. He isn't a pressure fighter nor swarmer. He thinks in the ring, nothing will change that.
Can't see that happening either... Canelo's camp is more like family than just a boxing coach/trainer relationship. Alvarez would have to self destruct before that camp is disbanded.
