Sergio is looking to fight Cotto should Cotto win his next fight, if they can make that fight at 157-158 then it is possible for him to fight Floyd in his next fight at 155-156, Martinez has been caling for the fight for a while.
Martinez is getting old and dropping down to 154 after all his injuries might not be a good idea Plus if Quillin or Golovkin get to him hes gonna lose that 0
a Mayweather/Sergio fight is irrelevant now. Sergio brings nothing to the table for floyd. I don't see Floyd moving up for anyone over 147 after Canelo. I can't see another option for Floyd next except the Matthysse/Garcia winner.
