I do see that Donaire will win this fight as he's facing a not ranked boxer here. Not degrading Santiago here but there's no big achievement yet he did even though he's currently at the peak of his career.
In this case, he can still show his skills and promote his next fight with lots of sales because we all know, he still has that flash speed and huge power when it comes to kinds of opponents like Santago. It's really hard for Donaire to retire because as of today, there is no Filipino boxer who is more famous than him who is still active because others are just a bunch of still climbing the ladder. He worked hard to get to where he is right now and to fully use it to his advantage until the end, it's just one of the wisest decisions in his life that he could ever make. Maybe he still can fight for another 3 or 4 fights if he easily wins this one.
Most people been saying that he's getting old, yes its true but he do still have that firepower and speed.Although it might not be still the same compared into those old prime days but still he could still give a good damn
shot and jabs that could knock down in todays opponent.There's still no word about retirement or whatsoever.They would really be planning on getting belts into the division on where Inoue had left.
If they do still able to dominate out that division and acquire several belts on that line up then retiring might be in mind but i do still doubt on that considering that Donaire do really comes
for the glory and not for money mainly.
