Every one that Manny faces throughout his career, they say the same thing. But once they feel the power of Manny Pacquiao, their whole game plan was thrown out. So this could be the same case here, but if Chihiro wanted a fight, Manny will give him to him.
If he stays very aggressive, Manny might be triggered and be poked and for sure the old version of Manny can comeback with fast and power left and Suzuki doesn't know what hits him.
Small to none, I would say, unless Manny didn't train or underestimated Chihiro which I doubt.
