Newcastle manager Alan Pardew says he was left "frustrated and disappointed" by his team’s defeat to Swansea in the Premier League.
A tight game had the deadlock broken just five minutes from time when substitute Luke Moore capitalised on a defensive mix-up between Davide Santon and Steven Taylor to win the game for his side.
The defeat ensured that Newcastle remain just six points clear of safety and Pardew lamented the manner in which at least one point was lost.
"We are frustrated and disappointed we did not even get a draw as we more than deserved that. We sat off them for the first 20 minutes of the first half but we sorted that at half-time," he told reporters.
"The goal was sloppy, it's a ball into the box, we had four defenders there and it should have been dealt with better; unfortunately it wasn't and it cost us."
Pardew also bemoaned his side's profligacy in front of goal during a concerted spell of pressure in the second half, with Moussa Sissoko and Yohan Cabaye thwarted by Swansea goalkeeper Michel Vorm.
"In the second half I thought they had settled for a draw, they knew they were doing well to stay in it," he continued.
"But when we did not score in that great period we had you know any mistake can be costly and that is what happened. We missed two or three big chances and you cannot do that at this level."
