- if you 're low lv, you can't earn some good money from friendlies because your stadium is small and the ticket price you must set to have fans, is much much lower than your official games. If you have a stadium lets say 100 K' (or more), it's a good source for getting extra money.
- The calculations in friendlies, is a lot different than official games. You can play with a team 10 levels above or bellow and get a draw .
- If you have a friend in your league and set a friendly to test your formation for a next official game, you just can't have any conclusions from that.
- You can earn some extra packs but if you have an injury then you 'll spend them
