In the past, I suggested cancelling matches in some response to real world local events. For example, Matches will postpone if the hometown of home team managers is facing Tropical Cyclone/Typhoon/Hurricane/Willy Willy. You know, the hometeam manager is busy on protecting himself at that time and have no time to play T11.
I also think about this before. I think this ought to be easier in some countries than others. T11 system may enhance to keep wealth, debt and nationalities of the referees. Assistant managers should suggest for good referee targets. In my opinion, we should use T11 cash, not tokens on this, because this is a T11 world event, not real world event.
Then T11 may also enhance to record whether the player is long/short hair.
I believe it is easier to implement for advertise sport shoes or underpants because this involves less system enhancements.
BTW, over weighed players like Wayne Rooney may advertise weight reduction plans. If their weight is lost, some attributes like speed or strength should also change.
