It was Liverpool’s first red card for violent conduct in Jurgen Klopp’s long reign and Van Dijk described his moment of madness as something that “should not happen.”
Van Dijk feels Nunez will be provoked in future games and has to make sure there is no repeat.
“He has to control himself, definitely,” the Dutchman said. “He has to manage himself. He has to be knowing that these things can happen, especially in the Premier League. It will be a learning curve for him and hopefully it will never happen again.
“Obviously he was disappointed and also probably with himself. But it’s a learning curve and we will always back him. He’s got the backing from us and he knows it should not happen again and hopefully it will be that way.”
Liverpool were trailing 1-0 to Palace when Nunez was sent off and Van Dijk was delighted with their reaction, including Luis Diaz’s spectacular equaliser.
He added: “I think with 10 men we played outstanding. We put them under pressure, obviously we took a lot of risk because we had to score the equaliser and were hoping to get the winner. But I think should not come with 10 men, it should not happen.”
He singled out Diaz for particular praise, saying: “A fantastic player. It’s obviously something we need and he provided that bit of special action and he can be so much better. He’s an incredible player already so we’ll see what the future brings.”
