This is one easier then u think if u boost it with a friend. First have you and your friend create a hevayweight fighter if you havent already, preferably one with no good skills. Create a heavyweight ranked match 5 rounds and CAF only. Get you and your friend in the same game. Now once the match starts just go in the middle of the ring. Both of you should now just keep tapping a punch button, dont do any combos, that way you are in less danger of knocking them out. Both of you should punch each other for one round. In the second round do this for only 1 minute. Then have one of you takedown the other and submit him. The winner of the match should be credited with 100,000 fans. You should get this within 10 matches.
