Option 1

Willow has some educational background with other languages and she is capable of speaking Swedish, Danish and Finnish, so hopefully the opposing player is from there because she would easily be able to sow the seeds of a fight eventually. If that method fails, option two is just hopefully Willow has a teammate who speaks whatever language their star player is and just use them there. If that still fails, there is the old tried and true method, just constantly hit the opposing player until he gets fed up and wants to fight. Big hits are a universal language and while one probably won’t start anything, three or four in a row, especially when Willow is going out of the way to hit them, that will get the blood pumping. Last method is the hail mary assuming all else fails, simply just pants the opponent and they will get the message and the fists will start flying.
