Before he can do that though, he needs to take down Bivol first who is also a strong boxer and currently a champion.
Canelo already has experience fighting at Bivol's weight class and I'm sure he can handle it.
What about scenario, if Canelo looses to Bivol? Canelo has experience fighting in light heavy, but against Kovalev, who (most experts think) stepped in the ring for a cheque or to sell his belt for few millions. Bivol is younger, faster, more hungry than Kovalev, who is more interested in punching women than Canelo in 2019. Even amateur career of Bivol is more successful than Kovalevs. Even though Canelo has experience in LH, this fight is going to a serious test for him.
