matthysse is far more technically correct than maidana, the only reason they are compared so much is because they're argentinian, if they both were american then they wouldn't be talked about as being identical fighters. matthysse hits you with straighter punches, he has a solid jab, he doesn't always rely on walking his opponent down as he can control from a distance with his jab and straight right. matthysse will control morales early, be cautious and take the rounds with his boxing skills, late into the fight he will increase his pressure and look to hurt and finish morales' great career. maidana could always only do one thing which was walk down morales and exchange with him and hope he hurts him, matthysse has more skills and options.
