Gordon Strachan cut a frustrated figure after Middlesbrough blew the chance of a first victory since he took over.
Former Celtic boss Strachan, who replaced Gareth Southgate at the helm a fortnight ago, saw his new side draw a blank for the first time on the road this season as they crashed 1-0 at Crystal Palace, their second straight defeat.
"When you have chances like that and you don't take them then you have a problem, luck has nothing to do with it," said Strachan. "It's frustrating, just like last week against Plymouth when our best player, Adam Johnson, missed a penalty."
"It's frustrating for me, it's frustrating for the players who work so hard and it's frustrating for the fans."
