Jurgen Klopp said being Liverpool manager is not just about "when the sun is shining" as he dismissed suggestions his squad is in decline.
However, they have struggled in the Premier League and sit ninth after winning only four of their opening 12 matches.
"It's not a quick fix but we will not stop fighting," Klopp said.
"People look at me and they say 'he looks tired' or whatever but I'm not. I cannot give that excuse. My job is not only to be here when the sun is shining and somebody gives us a trophy.
