Liverpool manager Jurgen Klopp has expressed his anger at his side's performance during the first half of their 2-1 victory over Swansea City this afternoon.

The Reds failed to register a single shot on target during the opening 45 minutes at the Liberty Stadium, going into the break trailing courtesy of a Leroy Fer goal.

Roberto Firmino and James Milner struck in the second half to turn things around for the visitors, but Klopp was still unhappy with his side's performance.

"I was very angry. I have lost a lot of football games, but today makes no sense. We were not ready and it is my responsibility. It was not good. The build-up was too static, no movement," he told reporters.

"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. It was not a day we should lose.

"I didn't think this would be a bad day, there was no sign in training. We lost patience and were moaning about decisions. We need to stop that. We were angry with ourselves, but we got cooler. In my job I can see that, but not change a lot until half time. It's important that when you are not brilliant, you are still able to win."

Liverpool's victory saw them climb up to second in the Premier League table having won four league games in a row for the first time under Klopp.
