Liverpool boss Jurgen Klopp says his team are only at the beginning of their exciting development.
Liverpool, with victory at Fulham, went two points clear at the top of the Premier League above second-place Manchester City, who have a game in hand.
Klopp said: "I am not in any doubt about my players' nerves. It is about intensity. We go for perfection but it is rare that you get it. People will say we need to be more convincing, but we are at the start of a development, not the end.
"They are cool enough. On our day we are a flying team, that's all there, but the consistency is rare.
"Let's go, let's go for it, let's fight, all that stuff. Today we set again the basis for the finish, and it's good. We only have to win and I smile all day."
