The Premier League has released their list of changes to commence on Friday, August 5th.
Here they are…
The clubs have agreed to allow the return of five substitutions this season. Teams will have the opportunity to make personnel changes on three occasions during a game, with an additional chance set to be granted at halftime.
The multi-ball system, which allows the game to resume with another ball when the match ball goes out of play, is to return, partly as an effort to speed up the game. In-game time last season average 55 minutes and 7 seconds, regarded as ‘unacceptable’.
Concussion trials are to continue for another season. Teams are allowed to make an extra substitution in the event of a suspected concussion. The Premier League is understood to be supportive of the idea of temporary substitutions, and is lobbying for it. It believes club medical staff should be given an amount of time to make a call without the substitute being permanent.
Premier League clubs have been advised not to stop games for a medical emergency in the stands unless absolutely necessary.
Assistant referees have been instructed to only delay raising their flag for an obvious offside when there is an immediate chance of a goal and very obvious attacking phase and tight onside/offside calls.
Clubs will be allowed to play friendlies while the World Cup takes place in November and December.
Massimo Marianella is reporting Arsenal has made contact with Manchester United over Marcus Rashford.
The Guardian has reported former Arsenal star Tomas Rosicky is a leading contender for the Gunners sporting director position.
Andrew Madley will be the head referee for the FA Cup match between Arsenal and Manchester United. There is no VAR in the third round of this competition. 
This is the right website for everyone who would like to understand this topic. You realize so much its almost tough to argue with you (not that I really would want toÖHaHa). You definitely put a new spin on a subject that has been discussed for many years. Excellent stuff, just excellent!
