Prolonging matches to tackle time-wasting is “changing the game we fell in love with”, the Professional Footballers’ Association chief executive Maheta Molango has said.

Referees in competitions around the world have been instructed this season to more accurately measure time lost to stoppages such as substitutions, goal celebrations, VAR checks and injuries, after the approach was first adopted at last year’s World Cup in Qatar.

It has already led to 13 minutes of time being added to the second half of Sunday’s Community Shield between Manchester City and Arsenal, and has sparked criticism from City midfielder Kevin De Bruyne and Manchester United defender Raphael Varane who say the move, combined with an already congested calendar, is pushing players to breaking point.

PFA boss Molango says the focus should be on sanctioning individual players and teams who waste time, and told BBC Radio 5 Live: “This is not basketball, this is football. There’s probably a reason why the game was 90 minutes and not 60, and what we’re trying to do here is change the football that we all fell in love with. That’s not, in my opinion, what the fans want to see.

“We all agree we need to deal with time-wasting. Whether the solution is to add more minutes to the game, I’m not sure. I think there are other ways to deal with that. The referee has the power to sanction the people who waste time.

“If you look at the game on Sunday, these are two teams that do not waste time. There was no time-wasting whatsoever yet in the second half you end up with eight minutes added with two teams who do not waste time.

“So you’re thinking when you see teams who use a different type of tactics, how long will the game be?”

Molango says many players have echoed Varane’s concerns over the new approach and player workload generally when he has met with them over the summer.

He says football must wake up and address the problems with the calendar, which appear set to get worse with UEFA’s club competitions expanding in the 2024-25 season. That campaign will also end with FIFA’s new 32-team Club World Cup in the United States.

“This year’s Champions League final is a good example of how saturated the calendar is,” Molango added.

“Watching the game as a fan it’s sad to see Kevin De Bruyne not able to finish the first half or to hear after the game Rodri say that they had cramps after 60 minutes. That’s just not what you want to see. What you want to see is players being able to show their best version.

“Those type of situations need to be a wake-up call to say you’re just not heading in the right direction and we need to do something about that if we don’t want to kill the product.

“I’m using the word ‘product’ on purpose because even for those who just see this as a commercial venture, ultimately they are killing the product. Ultimately it will affect the game and viewership.”

It has been reported that broadcasters are in talks with the football authorities over the new approach to added time amid concerns it will affect scheduling.
