The Reds boss is concerned about the safety of Premier League players as referees are reluctant to issue yellow cards
Jurgen Klopp says the Premier League must do more to protect players following the recent rule changes in the division.
Referees have been told to avoid giving fouls for "trivial offences" this season as the Premier League aims to let games flow instead of being interrupted constantly.
Klopp was concerned by some of the challenges that avoided punishment during his side's 2-0 win against Burnley on Saturday, as no yellow cards were issued despite 18 fouls being given in the match.
