Steve McClaren was left to bemoan a glaring miss by Siem de Jong as Newcastle failed to kill off bottom-of-the-table Aston Villa and were made to pay for it.
The Magpies were leading courtesy of Fabricio Coloccini's first-half strike when the unmarked De Jong was picked out beyond the far post by Georginio Wijnaldum's 57th-minute cross, but contrived to miss the target with the goal at his mercy.
Four minutes later, Jordan Ayew blasted home the equaliser which secured a 1-1 draw and just Villa's fourth Premier League point since the opening day of the season, in the process denying their hosts a third successive win.
McClaren said: "I have just seen it again – I have seen him thousands of times just put that in. I don't know, he was maybe unsighted – I think the defender just got across – but it was kind of defining moment.
"Two minutes later, they go and equalise, and then we have a bad 10-minute spell. But then I thought we recovered well from that and really went for the game at the end and again had two good chances with Gini (Wijnaldum) and Ayoze (Perez).
"So it's frustration, for definite, but the players – we should win that game with the chances. But that's football and sometimes you do, sometimes you don't."
