Magsayo needs to plan every strategy that he will use against Russell. A defensive fighter is the hard one to take down
it will take a lot of preparations for Magsayo.
He should seek some advice from Donaire, Magsayo sometimes does not conserve his energy, he loves to throw punches that are not accurate as he is thinking that he could KO someone who hits him without knowing his defense gets open. This is a title fight, a one time opportunity for some, so he has to carefully plan how to win this fight as it's a big-ticket to his future success.
Though Donaire and Magsayo are carrying the Philippine flag, they have different promoters.
Don't know if they are close enough for Magsayo to ask advise from Donaire.
If Magsayo is under MP Promotions, he is already in good hands but the work will still be coming from his end.
And Russell as a defensive fighter, that would really make a difficult fight as you really need strategy on how to connect with him.
This is a make or break for Magsayo, so he should not take this fight lightly.
