Alan Pardew conceded Aston Villa deserved to beat his Crystal Palace side on Tuesday and refused to criticise Wayne Hennessey for his costly error.
Palace have now failed to score in their last four league games and the closest they came at Villa Park was when Wilfried Zaha hit the post inside the first minute.
Hennessey’s error gifted Joleon Lescott the winner as Villa ended their 19-match winless run in the Premier League and closed the gap to safety to eight points.
“Wayne’s first touch puts him in trouble,” Pardew said. “He has been brilliant for us and his mistake cost us the goal but we made mistakes in other areas all night.
“They go unnoticed – as much as the goal is going to be a highlight for everyone else.
“I said to the players, there are not many times I can turn round and say we just couldn’t get going.
“I don’t want to take too much away from Villa. They deserved the win and my team didn’t play well.
“The Premier League would not want to lose a club of this magnitude. I hope they can resolve it.”
