League Bonus.

He gained a whooping 336 new fans compared to the 321 he had before the game. 336 is just about 3% of the ten thousand that watched the game. It isn't much, but it is significant to him. 

To top it off, he gained the league bonus after advancing to the professional league. This league bonus doubles his temporary destiny. That means he will gain twice as much power from each fan than before. 

The league bonus will increase once he advances to the leagues beyond the professional league. In the expert league, he will gain another league bonus that will increase the value of each fan to three. 

Then there is the master league, the legend league, and finally the champions league. The increase in league bonuses will make it easier for someone in a higher league to be stronger than those in lower leagues.
