Palace boss Alan Pardew, whose return to St James' was greeted with relative indifference, chose not to speak to the written press after conducting his post-match broadcast interviews, sending in assistant Keith Millen instead.
However, Pardew was in combative move when asked by radio journalists about Sunderland boss Sam Allardyce's suggestion that his players would have been "on the pop" all week after reaching the FA Cup final.
He said: "He hasn't got a case - just send him the video. They're prehistoric comments. I don't know what era he's in. Three or four of my players don't drink. Perhaps he meant Coca-Cola.
"It's nonsense."
Millen too responded to Allardyce's comments, saying: "They didn't affect us. We certainly know what we do. We want to finish the season strongly, there's no way we have come off it at all - you could see that in our energy levels today.
"We made it a really tough game for Newcastle, who are fighting for their lives. Sam can say what he likes about us, but we know we are very professional in what we do.
"We want to finish the season strongly - we have got an FA Cup final to look forward to, so we want to win a couple of games before that to keep this momentum going."
