freddie roach insisted on saturday that floyd mayweather does not deserve to be ranked alongside manny pacquiao as the leading fighters of their generation as the two boxers put the finishing touches to their preparations for the fight of the century in las vegas a week on saturday .
roach , pacquiao 's trainer , said he rated super-middleweight star andre ward and middleweight sensation gennady golovkin above mayweather despite the american 's unbeaten record and his status as hot favourite .
