Easiest way to get this is to boost in a group of 4 people, split into 2 clubs, each with 2 players.
Then arrange a friendly with the other club, exchange wins and you all have the trophy.
You can do this legit by creating or joining a club and choosing to search for a league match (not cup match, which is the automatically selected option) and win a game, however if the other team quits you won't get the trophy. You also cannot do this solo, it must be with at least 1 other person.
