Liverpool boss Jurgen Klopp has urged his players to focus for the full 90 minutes after suffering his first defeat since taking over from Brendan Rodgers.
The Reds suffered a surprise defeat at home as they lost 2-1 to Crystal Palace.
And Klopp says his players have to learn from Sunday's defeat.
"I'm satisfied with some moments but my problem is that you have to play for 95 minutes," Klopp said.
"If after the game you are satisfied with 60 minutes, sometimes it's enough, sometimes it's not. Today it's not. Of course, that's a problem.
"It's not a problem to lose a game, that's football and it happens all the time. But we have to learn the right things and if we learn the right things tonight, then it was very important that we lost tonight and good that we lost tonight.
"We have to learn that we decide how strong we are, we decide how good we are, we decide how awake we are, we decide how tired we are – nobody else.
"But one of the biggest [differences] between a very good game against Rubin Kazan and the game today was that there was only one thing to talk about – is it too much? Is it too much playing tournaments?
"I decide if I'm tired, nobody else. If you can start after 15 minutes, then of course you can start in the first second. Today we needed a few minutes to come in and it was too late for this game.
"After 15 minutes, when you saw this, nobody knows why they were 1-0 in the lead. That's how we have to play, we made many good things. But for today it was not enough.
"We have to learn that we decide; if everybody thinks that we gave everything we have tonight, then it's wrong.
"Of course we could do more – maybe not running more in this moment, but to be more awake from the beginning, to be clearer, to believe more. I don't want to use this word too often but we have to learn all this."
