Craig Pawson's decision divided opinion among former Liverpool players and current pundits, Jamie Carragher and Michael Owen, while Klopp clearly felt that the Toffees youngster had deceived the referee.
"But there is only one team playing and you give such a penalty, unbelievable. Yes". You give the penalty then one team can celebrate and we can't.
"I know people are saying Liverpool are flying and that, but today we need to be ready for a proper fight". I didn't use one swearing word. "When you stop Liverpool, the top scorers in Europe to seven shots on target then you are doing something right". "In my understanding it is not okay".
Klopp said before the match: "It is part of the season where you have to make the changes when you can make the changes". He said: "We needed just one opportunity and that opportunity came from a penalty".More news: How to watch the Geminids, 2017's best meteor shower, this week
"I have looked at it and he [Lovren] has pushed him, but we have seen ones like that before where it has been hard for the referee". I have been asked if that was a mistake, that it is my life.
Everton, meanwhile, had seen an immediate improvement in their performances following the appointment of Sam Allardyce at the helm last week, with the Toffees having notched 9 goals and conceded none in their last 3 outings versus West Ham, Huddersfield and Apollon Limassol.
'It's an extremely courageous decision to give that for us in a derby at Anfield and the referee got it right'. The Liverpool manager was adamant that his side had done enough to win the game, and if it wasn't for the referee, they would have had it.
The second-half began with Liverpool in the ascendancy, with Everton struggling to get the ball to their forwards, such was the home side's dominance.
