However, Gers boss Walter Smith believes his side deserved all three points.
"It was a good game," he said.
"From our own point of view we are a little bit disappointed with the defending, we gave away the goals a little too easily and had to work very hard to get ours.
"But there were a lot of pleasing things in our game especially in the second half. We created a lot of opportunities and maybe just deserved to edge the game with that second-half pressure.
"But give credit to United, I felt they played very well and they punished us for any errors we did make.
"In the end, we are pleased we managed to show a bit of determination and character in the end to come back and get a goal in injury-time to get the point.
"But we are a little bit disappointed overall because we maybe just deserved to edge what was a really good game."
