Jurgen Klopp finally got his wish at the start of this season after years of calling for change.
Frustrated by the growing demands being placed on his players, the Liverpool boss has been vocal in his wish for the Premier League to increase the number of substitutions managers are permitted to make during matches.
A first glimpse at five changes being the norm was witnessed during the 2019/20 season at the time of Project Restart as clubs were given additional help in response to the coronavirus pandemic. But Premier League clubs voted against keeping the arrangement in place ahead of the 2020/21 despite a number of top European leagues utilising it. It has, however, been utilised in the Carabao and FA Cup for the last two years.
