Liverpool manager Jurgen Klopp said he was not worried by the smattering of boos that greeted the half-time whistle during his side's 3-0 win over Huddersfield at Anfield on Saturday.
Mohamed Salah missed a penalty before the break as Huddersfield, managed by Klopp's close friend David Wagner, kept the scoreline goalless.
But after watching second-half strikes from Daniel Sturridge, Roberto Firmino and Georginio Wijnaldum secure victory, Klopp said: "I would not make a big deal out of it.
"I have heard bigger atmospheres in my life when you know something is wrong here. It was not nice to watch [the first half] -- it was just work.
"When you go to watch football you do not only want to see work, that's how it is."
Salah's penalty was his first for Liverpool, but he fired it too close to visiting keeper Jonas Lossl, who saved.
He had been given the job after Roberto Firmino's Champions League miss against Sevilla and his own conversion of a stoppage-time penalty against Congo that sent Egypt through to the World Cup finals.
Klopp suggested a change of taker could be a possibility, with striker Daniel Sturridge one potential option, but added: "I thought it made sense [to give the role to Salah] after the Egypt penalty -- obviously the pressure is bigger in Liverpool than in Egypt to qualify for the World Cup!"
