Kieran Trippier says that Jurgen Klopp should speak to referee Andre Marriner if he has any serious complaints about time wasting.
Klopp flagged up Newcastle's methods of eating up the seconds during the 2-1 win which came courtesy of a late winner from Fábio Carvalho. United's defeat was inflicted in the 98th minute - something Klopp felt Newcastle deserved after trying to run the clock down.
Trippier said: "That's something the referee needs to get control of. We're coming away to Anfield, we set out a game plan so if he wants to complain about time wasting the referee and the officials have to take control.
