Jurgen Klopp blamed his players for becoming embroiled in a fight at Swansea City as they lost their unbeaten 18-match run to the Premier League's bottom club. It was Liverpool's first defeat since October, but the points were priceless for Swansea, who cut the gap between themselves and those above the relegation places to just three points. He said, "I am more frustrated about the performance than the result. "We were just not good enough, especially in the first half. We didn’t play how we wanted to play."

Klopp added: "Swansea knew that to win today they needed our help and unfortunately we gave it to them. “They did the right things to deserve to win a game like this tonight and we didn’t deserve it. We could have equalised at the end, but didn’t have that luck."
