But a tournament that is held every two years is a problem in my mind as now players will need to play twice as much for their national teams, and I have no doubts that many will decide to retire and not participate with them in order to avoid injuries, decreasing the importance and skill level of the competition in the process.
For example when Spain was able to win the World Cup by the time it took to hold the next World Cup the team was nowhere near as good as it was and they failed to repeat as champions, however if the World Cup is being held every 2 years then it will be way too easy for a good generation of players to repeat and win the World Cup back to back, diminishing in the process the feat that has only be done by Italy and Brazil.
