Liverpool boss Jurgen Klopp was left frustrated with their defending is defeat to Swansea City.

Having gone 2-0 down they drew level thanks to a Roberto Firmino double but then undid their good work by allowing the unmarked Gylfi Sigurdsson to score the winner.

"The most disappointing moment was the third goal," he said.

"There was nearly everything wrong with this goal: it started with a long ball and the reaction was not good.

"We scored and then we couldn't switch to defence mode and that was the biggest mistake in this situation.

"We were passive and they took the opportunity.

"The defending around all three goals was not good enough. That is a very important part of the game and was very disappointing today.

"Today it was a big opportunity for us to get three points and that is what makes it so frustrating.

"We gave them the opportunity to win the game so they are deserved winners."
