Jurgen Klopp 'angry' after Liverpool lose at West Ham
Liverpool manager Jurgen Klopp said he was "angry" after his side "deserved" to lose against West Ham United at Upton Park on Saturday.
Headed goals from Michail Antonio and Andy Carroll handed West Ham a 2-0 victory over the Reds in the Premier League.
Klopp, whose side went into the match having won their previous two games, was not pleased with how his players performed.
He told BBC Sport: "I'm really angry today because we could have got so much more because everybody could see in the moments we play football what could happen. Today, we deserved to lose.
"We always had the ball, we could have made much more chances but we didn't. We have to again accept that we didn't play like we should."
Klopp felt left-back Alberto Moreno was fouled in the build-up to West Ham's 10th-minute opener, when Antonio thumped in a close-range header from Enner Valencia's cross. But he was even more annoyed with his side's defending nine minutes after the break, when Mark Noble's floated cross was powerfully dispatched by Carroll against his former club.
"It was five against one, near the sideline, and nobody won the ball,'' said a disbelieving Klopp. "Then cross, Andy Carroll, 2-0, thank you very much! If you know the other team has Andy Carroll, how can you allow crosses?
"It was not enough from my team today. The decisive moments we were there, but we were not there 100 percent.
"We could have done much better. We had our moments, we tried, but if you fight at 95 per cent then it's not enough.
"It's my responsibility. I'm angry about myself today.''
West Ham could have scored more, with Manuel Lanzini hitting a post with a vicious, swerving drive and Simon Mignolet saving well from Aaron Cresswell's deflected shot and another Carroll header.
Yet Liverpool could still have snatched something from the game, as Emre Can hit the crossbar at the end of the first half and Lucas had a header cleared off the line towards the end of the second.
But the day belonged to Carroll, who celebrated wildly after scoring a goal against the club who let him leave just 18 months after signing him for £35 million.
"I thought he was brilliant,'' said Hammers manager Slaven Bilic. "Not just because of his goal but his performance; defending, holding the ball up, pressing their defenders, everything.
"Liverpool is always a 'target' team, especially now with Jurgen Klopp as their manager, and to create chances and keep a clean sheet is a great way to start the new year for West Ham.''
