Saturday's draw with Burnley means Firmino is yet to score at Anfield this season.
Klopp said, "It cannot become a psychological problem because Bobby played today an outstanding game and we don't judge him. So I hope he will not read your newspaper if you make a story of it because we just don't think about it. It's not important who scores. We need Bobby for other things, we need Bobby in exactly the spaces where he was today, we need him as a link-up for all the other things.
"We only have chances in other positions because Bobby plays the way he plays. And he will score, there is absolutely no doubt about it. We are not worried at all about that because he played an outstanding game today and was involved in so many decisive situations. In the end, nobody really scored apart from Robbo with a header, which is pretty exceptional. It will not become a problem."
