Former welterweight champion Andre Berto is very interested in a potential fight between IBF welterweight king Errol Spence and current WBC, IBF lightweight champion Mikey Garcia.

In the last few weeks, Garcia (39-0, 30 KOs) has made it clear that he's willing to move up by two full weight divisions, to the welterweight limit of 147-pounds, to challenge Spence (24-0, 21 KOs).

Berto believes Garcia sees something that he's confident of exploiting in Spence.

"I think a guy like Mikey who has been in the game for a nice bit of time and his family has been in the game like they have, I think Mikey sees something," Berto said to CBS Sports.

"I think he sees something and I don't think he would try and make that jump if he wasn't confident in some type of sense. I think he has seen something in Errol Spence that he believes he can probably take advantage of."

"Between fights, Mikey gets pretty big and I know for sure some time ago he sparred with big guy. I know he helped [Marcos] Maidana get ready for a a few fights as well and I heard that he really, really held his own with Maidana. I don't think it's going to be too much of a crazy jump for him, but of course it's going to be a crazy challenge. But just like when [Manny] Pacquiao fought De La Hoya, we all thought he was outrageous for doing it. After he saw something, he came out victorious.

At the same time, Berto believes Spence is going to be very motivated to do as much damage as possible on Garcia to prove a point to anybody else who's thinking about testing him.

"But of course, Errol Spence is a different beast. He's still young and he's hungry and he's going to want to probably make an example out of Mikey Garcia for trying to test him like that but I think it's going to be the type of fight that Errol isn't going to take Mikey lightly. If he does, it's likely going to be a problem. Mikey has everything to gain from that type of fight and Errol has everything to lose," Berto said.
