Munguia is never in a boring fight so I am sure against Canelo it will be a slugfest. Munguia's porous defense is his biggest weakness and would probably be his downfall against Canelo.

The boxing community will be eager to see how this potential matchup unfolds and whether Munguia can overcome his defensive challenges in a bout against a top-tier opponent like Canelo,

I would love to see Munguia vs Berlanga first though, As Canelo as his 3 fight deal with PBC, with 2 fights remaining, Benavidez could be the next or Morrell. But in case of Munguia him and Berlanga would be a rivalry if Canelo says no.
Berlanga will have a fight against Padraig McCrory in February 24th, and if he wins impressive, then Hearn and Oscar could sit down and this is a Mexican vs Puerto Rican, which has a storied rivalry in Boxing history.
