Liverpool manager Jurgen Klopp says the Premier League “has to change” its fixture scheduling, with Manchester City counterpart Pep Guardiola adding that players are not protected.
It follows Ole Gunnar Solskjaer’s criticism of match timings, with his Manchester United team kicking off at 12:30 GMT on Saturday after playing on Wednesday in the Champions League.
Liverpool and Manchester City played out a 1-1 draw on Sunday after also both having had European fixtures in midweek.
Klopp told BBC Sport: “The boys are on the edge. No team on a Wednesday night should have the 12:30 kick-off on Saturday.
“Sunday – no problem. Not the 12:30 because that is a complete killer. You wake up and play football. This is the recovery phase.
