Nunez was shown a direct red card in Liverpool’s 1-1 draw with Crystal Palace for a header on Joachim Andersen, meaning he will miss the upcoming matches against Manchester United, Bournemouth and Newcastle.
That leaves Liverpool with even more problems as their side become increasingly stretched with just two games left in the season, neither of which have been won.
While Klopp was frustrated by Nunez’ moment of madness and failed to recognize the striker as he walked away, the Liverpool boss hopes the spell on the sidelines could prove beneficial for the new signing.
“Of course he was a red, he was provoked but that’s not how he should behave,” Klopp said.
“Darwin knows he let his teammates down. I’m going to talk to him. It doesn’t make sense if I talk about it too much now in public.
“It was definitely not a reaction we wanted to see. He knows he will be challenged in this way, the centre-halves will do that, he’s tough, but it’s not a reaction we want.
“There is now time for another pre-season, that’s the situation. We are going to use it for physical work to make it strong, not a punishment but to make it even stronger.
