West Ham United boss Sam Allardyce branded their finishing as "miserable" after defeat to Crystal Palace.
The home crowd grew increasingly hostile in the second half, jeering Allardyce's substitutions and booing at the final whistle.
The Hammers boss admits he has sympathy with the fans' frustrations, but believes his team could have taken something from the game had it not been for some "miserable" finishing.
"In the end it's about one thing," Allardyce said. "When you get the opportunity to score you've got to score and that's what we didn't do today.
"We were pretty miserable in our finishing. Not making the keeper make more saves than he did was my big disappointment apart from the penalty given away.
"Our quality of finishing wasn't good enough when we created the chances we did and you don't create many chances against Crystal Palace."
