The Portuguese Football Federation (FPF) wants to test the idea of two 30-minute halves at the Under 23 Revelation Cup, according to i Sport.

According to CIES Football Observatory, 60 minutes and 59 seconds is the average time the ball remains in play during Premier League games and the latest trials aim to stop the clock when the ball is out of play, therefore ensuring there is less time-wasting and that the overall quality of the game is improved.

Reports also mention that Premier League teams like Manchester City and Liverpool lead the table when it comes to keeping the ball in play longer than the rest as well, with 60 mins and 56 mins respectively. Southampton and Aston Villa were on the other end of the spectrum with 52 minutes and 51 minutes respectively. 

Meanwhile, Newcastle have gained the most by keeping the ball out of play, as games involving the Magpies featured four times in the list of top ten games in which the ball has been in play the least, helping Eddie Howe's side climb out of the relegation zone. 

The trials conducted by FPF will only be considered official once International Football Association Board - the organisation responsible for football laws, gives its approval.
