If your trainer didn't think you won that fight, nevermind being robbed, then yes it's time for a new trainer. It's one thing to give Canelo props for that fight, but not making a case for why your fighter should have gotten the win is an unovercomable gap in views IMO. Especially when it's truth and thus very easy to make that case. Eventhough fighter and trainer ought to be on the same team, in this particular case it's not even asking for Sanchez to be biased. Go figure...
Canelo could end up with one of the all time great iron chins which makes a mockery of both fights where it was said Golovkin needed a knockout to win,some will have no sympathy as he knew what he was up against but in all honesty what kinda bull **** is that. Canelo could take Wilders bombs and not get knocked out lol
