Liverpool manager Jurgen Klinsmann has attributed part of his team's disappointing 4-1 loss to Napoli in the Champions League on Wednesday to their defense.

With goals from Piotr Zielinski (2), Andre-Frank Zambo Anguissa, and Giovanni Simeone, the Reds were three goals down at the half.

Luis Diaz only managed a consolation goal as Napoli managed to win 4-1.

“The start with the two penalties." First and foremost, Napoli played a really good game and we didn’t. That is the first explanation for the defeat, "the German told BT Sport."

“The two penalties we concede are both – for sure one – a little bit unlucky, but maybe you give them, only one goes in."

“Then the next two goals we served on a plate. That’s not cool and we should defend better in the first place and then in the last moment as well,” Klopp explained.

He said although his team had some chances, they were never in the game as they were not compact both in attack and in defence.
