Vikings Vs Roman Legions.?

throw your therioes who would you reckon, would be victor in a battle, if these to fierce forces ever did meet. viking's that were like todays modern age rocker bikers with big grizzly beards, and full off shear power, capeable of lifting a man of the ground by his phist ? armed with axe's and brute swords, or would the romans dicipline prevail ? romans moderatly armoured, however i dont see there armour stopping the brute force of a viking. i reckon a 2h sword smashed against a roman with shield would make a roman soilder go flying. ''' romans were not big and fierce'' small in height and not muscler as a viking. ? what do use reckon.
