Hey there,
I'm trying to make an ERD for a Soccer Predictor (betting) Database.
The Database should be able to list the Teams, Betting and the User.

It's my first time designing a Database and I don't really know how to make the ERD so that it contains
every aspect needed.
I started designing a simple relation shema based on the aspects:

Team(Team_id, teamname, country)
User(user_id, name, forename, points)
Game(game_id, team1, team2)
Bet(bet_id, prediction, earnings)


So now I'm stuck with actually creating the ERD, and I'm not sure if I could add some more relations or
attributes.

I hope it's clear what I want and I hope you can help me.
Thank you
