Following Canelo's history-making, impressive win and debut at 175lbs over Sergey 'Krusher' Kovalev to win the WBO light-heavyweight world title, British rival Callum Smith reminded him who the man at 168lbs is.
The Liverpudlian who won the World Boxing Super Series in 2018, with a crushing KO of 'Saint' George Groves said, "I think he will come down, whether he goes to 160lbs or 168lbs, I've no idea.
"If he comes to 168lbs, I believe I'm the number one in that division, so he'll have to come and beat me to take that place.
"But I'm not going to waste my career waiting for a fight that might never happen. If it happens, it happens. If it doesn't, there's still plenty of other big fights."
'Mundo' defends his WBA World, WBC Diamond and Ring Magazine Super-Middleweight titles mandatory challenger John Ryder at the M&S Bank Arena Liverpool on Saturday November 23, shown live on Sky Sports in the UK and DAZN in the US.
Canelo KO'd 'Krusher' in the 11th round of their WBO light-heavyweight fight to become just one of a select few of Mexican's to ver win world titles at four different weights. Two judges had the bout even at 95-95 after the 10th round, so Canelo is unlikely to remain at the highest weight he has ever competed at or go higher as some fans have questioned if he could go up to crusierweight. His move back down to super-middleweight or middleweight will likely happen for his next fight. The middleweight trilogy with Gennadiy Golovkin is still being called for, but Eddie Hearn has strong beliefs that Billy Joe Saunders will get the fight with Canelo on Cinco de Mayo next year.
