Jurgen Klopp calls for clarity on time-wasting offences after Trent Alexander-Arnold booking against Chelsea

Jurgen Klopp called for clarity on time-wasting offences after Trent Alexander-Arnold was booked for taking too long over a throw-in during Liverpool's draw with Chelsea on Sunday.

This season has seen the introduction of measures to try to keep the ball in play for a greater proportion of matches, with significant increases in added time seen over the Premier League's opening weekend.

It is hoped that adding on time to reflect the length of pauses to the game will deter players from delaying the restart of play.

But Klopp believes the yellow card shown to Alexander-Arnold in the 67th minute at Stamford Bridge whilst the score was 1-1 was unfair since the defender was looking for a player to throw the ball to.

"I think last season some teams stretched it, definitely," he said. "And we are not one of these teams, we never were. I knew we would get a yellow card - probably the first yellow card - for time wasting with a throw-in.

"When Trent is looking for a player and tries to find a player, this is a tactical thing - he cannot just take the ball and throw it.

"Maybe we have to clarify it a little bit, but besides that I think too many teams stretched it and did it too obvious and that's why everybody thinks we should watch a bit more football.

"I don't know exactly what the net ball in play time was today, but that's how it is now. It was not a problem today for me, to be honest. What was it, first half six minutes? Because of the VAR decisions. And second half, five, I think.

"That's a lot but this is a time where we try to sort it like that. I am not sure that will last forever but at the moment it's like that and we have to deal with it."

Liverpool led early in west London thanks to Luis Diaz's well-taken breakaway goal and
