What is the most opposition supporters at one game?

I have just played a cup game and my opponents had 12 friends supporting them, giving them a 19% possession advantage. Is this a record? It's the most I have ever seen.
Prior to the game 1 of these supporters tried to become my friend, presumably to arrange a friendly just before the game to weaken my team. I turned it down. They seem to be taking this game far too seriously lol

Thats impossible. The cap for possession is 15% for either side.

Sorry, I meant 15%, typo
