Alan Pardew was disappointed after his Newcastle side succumbed to a late goal in their 2-1 defeat at Arsenal.
Newcastle took the lead at the Emirates through Hatem Ben Arfa, but their advantage lasted less than a minute before Robin van Persie fired the Gunners level and Thomas Vermaelen then scored the winner in injury time before the final whistle.
Magpies boss Pardew felt that after the commitment shown by his team, summed up by Danny Simpson playing on with injury, they deserved to take at least a point away from the Emirates.
"Last minute defeats are galling. Unfortunately our right-back, Danny, got injured and we couldn't replace him as we had already made three subs," Pardew told Sky Sports 1 HD.
"The sort of effort we put in tonight, it was a really committed performance to try and get something against a side that are really in form.
"The pushed and they pushed and unfortunately we didn't have the legs left at the end to see it through.
"We switched off after we scored and almost gifted them the first goal.
"But we've defended well. We could have a bit more threat and keep the ball a bit better. But it's difficult, they are a tough team."
Pardew felt the result may have been different if his team had held onto the lead longer, but admits that in the end they just could not match the Arsenal fitness levels.
He added: "That might have made a difference, but I think really we put such an effort in that we were just running out of steam.
"The five extra minutes did not help us, you could say that they put those on for this and that."
Newcastle, though, could have been architects of their own downfall after much of that stoppage time was added on for Newcastle goalkeeper Tim Krul taking as long as possible over each goal-kick.
"The goalkeeper is going to take his time, we're doing such an effort we have to wait for our strikers to get set and we're away from home," said Pardew.
"Maybe he took a bit long with one or two, and it is frustrating for home fans, but you couldn't fault us for commitment or effort and we have to make sure that last-minute goal does not impact Saturday's performance because obviously we are very, very disappointed.
"We've had such a great season, but even in great seasons you're going to have days that do not go your way. I cannot look anyone in the eye in there and say they did not deserve something from the game."
