i paid my players max in both games.
my conditions were the same (his could have differed of course, but i doubt it since he was using other players in his previous game in both days).

yes there is a factor called luck. But luck cannot contribute for 4 goals while my players miss the goal shot after shot after shot after shot after shot after shot.

Also - how does HIM paying his players lead to my players missing the goal whenever they attempted a shot?
