Jurgen Klopp believes Liverpool were too impatient as they slumped to a 3-2 defeat away at West Ham.
The Reds fell behind to an early Alisson own goal, before Trent Alexander-Arnold equalised from a free-kick.
But second half strikes Pablo Fornals and Kurt Zouma saw Liverpool lose control at the London Stadium.

And even though substitute Divock Origi halved the deficit late on, it wasn't enough to preserve the Reds' 25-game unbeaten run.
Speaking to reporters after the final whistle, Klopp insisted his team had been in control against the Hammers only to come unstuck because of poor decisions.
"First half, completely in control of the game anyway, the German said.
"1-0 down because of a set-piece. We scored the equaliser. A wonderful goal and were really in control and in charge of the game.
"Obviously West Ham plays really good stuff this season but today it was a bit more like the old West Ham, going for set-pieces and counter-attacks.
"So first half we didn’t let that happen apart from one set piece if I am right, at least where they scored the goal.
"Then in the second half we lost balls in the wrong places, in general, we lost more balls than in the first half.

"They scored from a counter-attack and from a set-piece, the second one was exceptionally well-taken and a fantastic finish from Zouma, but that all shouldn’t have happened because we should have controlled the game still in the second half."
He continued: "For whatever reason, it looked to me like we lost patience.
"We didn’t have enough clear-cut chances so we wanted to change the wrong things.
"Actually our passing changed too early. We had to do that higher up the pitch where you are better protected than in the situations where we lost the balls."
