Fantasy battles

Fantasy football (soccer).

Before a league matchday, two fantasy managers pick each a fantasy team of 10 players: 3 defenders, 4 midfielders, 3 forwards.

Each player is paired against a player from the opponent fantasy team: defenders against forwards, midfielders against midfielders.

Before the matchday, for each real team the expected result is computed, just considering average goals scored vs. average goals conceded by the opponent team (home or away, depending on the fixture).

Then, the fantasy score of each player is given by:

• defenders: average goals scored - goals actually scored by the opponent real team
• midfielders: actual goal difference - average goal difference of the opponent real team
• forwards: actual goals conceded - average goals conceded by the opponente real team

Then you compare the fantasy score of each pair of player in the two fantasy teams, and each point of advantage means (in order):

1. midfielder: one offensive chance for his fantasy team
2. defender: one less chance for the opponent fantasy team
3. forward: one goal for his fantasy team (if there are enough chances)
