The Reds saw their first loss after a series of 44 games.
"They did exactly what they wanted to do, we did not. That's how football works," Klopp said in an interview.
"The first half was a tough one, a lot of second balls, running here and there, we had the ball a lot but we didn't come in the right positions to cross, the right positions to finish, against a really good, organised side, with a top set-up for this game,” he added.
Liverpool, with 79 points, leads the Premier League standings. The next match the club will play on 7 March at its home field against Bournemouth.
