Liverpool boss Jurgen Klopp was angered by their performance in defeat at West Ham.
Headed goals in each half by Michail Antonio and Andy Carroll made it back-to-back wins for the Hammers and ended Liverpool’s Christmas revival.
“It’s no day for being disappointed, it’s a day for being angry,” Klopp told BT Sport after the game, and that emotion lasted until his full press conference.
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 per cent.
“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.”
