**Another change to the game was discussed in 2017, with the plan being to reduce the length of a match to 60 minutes but to stop the clock every time the ball went out of play. The discussion was part of an IFAB proposal entitled 'Play Fair!' and was based on the idea of players time-wasting too much. In most 90 minute matches the ball is in play for less than 60 minutes.**
