Jurgen Klopp has warned England will suffer at next summer's European Championships if the Premier League persist with the rule of three substitutions.
Liverpool manager Klopp has long advocated the need to increase the amount of changes possible to five, as was the case when football resumed after lockdown, and a number of his counterparts - such as Manchester City boss Pep Guardiola - have supported his views.
Klopp is concerned a schedule that will see the majority of teams play at seven times before the turn of the year is going to have an impact on the fitness of players, particularly those clubs who are also juggling European commitments.
