I think the ideal number of substitute in football game should be a maximum of five. The flowing are some of my reasons

1. This will allow more players to get the opportunity to show what they are capable of. Some players are just on bench just because their team have exhausted their total number of substitute.

2. It will ease the pressure on some of the players. Playing football for total of 90 minutes is not an easy task. I believe it will create room for some players who get tired in some matches to be substituted and others brought for better game.

3. It will make the game more interesting to watch and partake in activities relating to it. In some games that runs to extra time, it is mostly seen that most of the players are tired. I believe that when five substitute are been made it will give the game a new strength and the energy to make the tension increase will rise. At he end i think it will give a good game with great momentum.
