1. Make sure the match balls to be used at the World Cup are the same as that used in the previous year's Confederations Cup and all international tournaments in between. The outer print / design can be different, but why should a completely new ball manufactured with new material / technology be used for the first time in a World Cup?
2. Introduce video referal system. When we have someone watching the match on high definition television with super slow-mo reviews from different angles, and we have the referee / assistant referees on the field, running and judging with thousands of vuvuzelas buzzing around them, you know who will get the decisions right!
2a. In all cases where the players are sure the referee has got a decision wrong, they should get a chance to challenge that. It is there in Tennis, Cricket, etc and there is no reason why it can't be there in Football. There is no reason for a player wrongly given a red card to sit out one / two matches, just because the referee got the decision wrong. In a tournament like World Cup, that incidence can be a differentiator.
