The 26-year-old is struggling to fathom his side's current plight.
Shot stopper Tim Krul saw both sides to the argument after Newcastle's 2-2 draw at Swansea.
The Dutchman knows Alan Pardew's men could have left Wales with less than a point.
The result leaves Newcastle in 18th place and Krul insists a club of their stature should be fighting for a top-ten place.
"I've got mixed feelings if I'm honest, because I thought we could have snuck it at the end," the goalkeeper told Newcastle's official website.
"Don't get me wrong, it was great to come back and to do that twice. When you go one down, confidence is low, then come back to 1-1 and do it all over again to make it 2-2, it's a good thing.
"But we can't just be happy with a point because we should be fighting for spots in the top ten.
"Some people might have taken a point before the start of play, away from home at a team like Swansea, but not me. I'm more ambitious than that.
"However, we showed good spirit and that is a big positive to take from today."
