The Reds played out a goalless stalemate with Manchester United on Sunday, taking their goal tally to one in their last four matches.
"If we won 1-0 I'd think it was completely fine. You can't deny Manchester United chances for 90 minutes. You never could. They're in a good moment," the German coach told Sky Sports.
"With all the things said before the game – they're flying and we're struggling – my boys did a good game tonight.
"First half the counter-press was great, passing was good. But we didn't score. That's the most important thing in football.
"The second half was a bit more open. They had two big chances – Alisson made two good saves.
"There is no easy explanation [for their recent lack of goals]. You always miss chances. You have to keep going and try to ignore the talk around it. Everyone wants to see goals. You cannot force it.
"It's football. These moments happen. You have moments where you can't explain why you score from all angles. Against Crystal Palace everything ended up in the net. It's a bit annoying in between these moments.
"I like the game. I saw a lot of really good individual performances and the team performance was good. Not the result we wanted, but the result we got."
