Liverpool news: Ex-Premier League referee has major concern as Jurgen Klopp helps trigger law change

Keith Hackett has warned teams like Liverpool can exploit the permanent introduction of five substitutes to “waste more valuable time”.

Speaking exclusively to Football Insider, the ex-Fifa and Premier League referee admitted there is a valid reason for the increase in the number of substitutes.

IFAB revealed last week (13 June) that they had formally written in the permanent introduction of five substitutes into the laws of the game for 2022-23 at their AGM in Doha.

It was temporarily introduced to ease the load on players when football resumed following the coronavirus pandemic in May 2020.

The Premier League then ditched it for the 2020-21 and 21-22 seasons before they announced earlier this year (31 March) that it would return for 22-23.

Jurgen Klopp has been a strong proponent of the change and, as quoted by ESPN earlier this year (7 March), insisted it was “essential”.

“Substitutions by their very nature are tactical,” Hackett told Football Insider correspondent Connor Whitley.

“This also might be around health issues. There are better measurements of players that are fatiguing therefore I think there are other spin-off benefits. Players who are fatiguing are at risk of getting injured and therefore bringing on a fresh pair of legs is a good idea.

“My one concern is, is this going to be a tactic to waste more valuable time? It’s almost like a cruise liner’s docked and the passengers are marching off.”

Clubs were allowed to use five subs in the 2021-22 Champions League, FA Cup and EFL Cup.

Liverpool lifted both the FA Cup and EFL Cup last season and reached the Champions League final meaning they played 63 games – the most possible in a domestic English season.
