1- i suggest there is a reward on goal difference when you win.
Example:
Win 7-2 does not equal win 1-0
suggestion
Each goal difference 1 K or 10 K (best)
2- Buying from the store by tokens and cash
All sales have two values: the value of the tokens and the value of cash
Each player chooses buy any one of them
3- Make it possible to purchase tokens with cash .
note: I do not speak English so this automatic translation from Google.Sorry for that
