It was previously revealed that their fight will take place on May 4 at the T-Mobile Arena in Las Vegas, USA.
"I like this fight. Do I believe that Alvarez can take it early? Yes, I do. Come on, he's been shaken before. I know Munguia's style will give Canelo problems and we're looking forward to this fight. We signed the contract in one day - that's how much we wanted this fight.
I think Alvarez has given up a little bit, but we'll find out. I don't expect a knockout, but Jaime can knock him out," Boxing Social quoted Roach as saying.
