Jurgen Klopp said he was not worried about the nervousness of his players after Liverpool's 2-1 victory over Fulham at Craven Cottage.
Sadio Mane gave the visitors a lead in the first half, but former Liverpool striker Ryan Babel took advantage of a confusion between Virgil van Dijk and Alisson to tie for Fulham before James's penalty kick Milner marks the three points of Klopp's men.
The victory brings Liverpool back to the top of the Premier League with Manchester City two points behind second place after playing one game less.
"We started very well and did a lot of good things, but we lost our pace," Klopp told Sky Sports. "I am not the most experienced manager and I have similar problems after the Champions League matches.
"First half a little rusty, the second half we could have finished and then it's clear to 1-0 if you do not kill it, it can happen … Babel was there, that's how football happens .
"They deserved a goal but we deserved three points – a brilliant afternoon, I have to say.
"I do not doubt the nerves of my players.It is a question of intensity.We aim for perfection, but it is rare that you get it.Burnley, [Bayern] Munich, Fulham – you must adapt. People will say that we must be more convincing, but we are at the beginning of a development, not the end. "
