Terence Crawford's trainer, Brian McIntyre, believes he has the key to stopping Canelo Alvarez's pursuit of more world titles. McIntyre, who guided Crawford to victory over Canelo, is now backing 30-year-old Lester Martinez, who has only 20 fights under his belt. Martinez, from Guatemala, is seen as a potential world title contender, especially with McIntyre's guidance. The trainer highlights Martinez's ability to adapt and overcome weaknesses, drawing parallels to Crawford's own success. Martinez's recent split-decision draw with Christian Mbilli for the WBC interim title adds to his credentials. With a rematch ordered and potential future defenses against Canelo or Immanuwel Aleem on the horizon, Martinez is poised for a significant career leap, and McIntyre is confident in his ability to rise to the occasion.
