Saul "Canelo" Alvarez (44-1-1, 31KOs) is ready to face anyone. On Monday, the Mexican star officially switched his network affiliation from Showtime to HBO. And now he's ready to face all of the stars under HBO's banner, including IBO/WBA middleweight champion Gennady Golovkin (30-0, 27KOs).

Canelo will return to HBO in December and then there is heavy talk of a fight with WBC middleweight champion Miguel Cotto in May.

"It's a possibility. There are two guys there [Golovkin and Julio Cesar Chavez Jr.] that would be good fights. I'm willing to fight anybody," Canelo said.

Canelo sparred Golovkin in the past and has a lot of respect for him.

"It was very good sparring. He's a very strong fighter, very strong. We helped each other out and what can I say about him....he's a very good fighter and he's a nice person as well. He's a very nice person but this is a sport, this is a business - and if I have to fight him - no problem," Canelo said.
