Liverpool boss Jurgen Klopp was far from happy with the performance of his side as they came from behind to beat Swansea 2-1.
Liverpool - who lost Adam Lallana to a first-half groin injury which has ruled him out of England's World Cup qualifiers against Malta and Slovenia - were below-par in south Wales as they trailed 1-0 at the break to an early Leroy Fer goal.
But Roberto Firmino and James Milner rewarded a much-improved second half performance to secure a 2-1 win and hand Liverpool a fourth straight Premier League victory.
Even so, Klopp was far from happy with his players and says it took a half-time blast to get a response from them.
"I was very angry. I have lost a lot of football games, but today makes no sense," Klopp said. "We were not ready and it is my responsibility. It was not good.
"The build-up was too static, no movement. We were never compact enough and we lost a lot of balls. We got better in the second half and when we let the ball roll it became difficult for Swansea.
"The second half was better, but still not brilliant."
