Bournemouth manager Eddie Howe admitted his frustration after two late goals allowed Oldham to secure a 2-1 victory.
Bournemouth who went in front just before half time when Rhoys Wiggins hit a free-kick from near the right touchline and watched it sail all the way into the far corner.
Yet Oldham equalised in the 78th minute through Kieran Lee and Ournare Tounkara slid in for a close-range winner.
Howe said: "The frustrating thing is that we conceded twice when we did not look like we were going to concede at all.
"Oldham didn't really have any chances apart from the goals and I thought we were going to see it out comfortably.
"We had control and I could not see that changing but it isn't the first time we have conceded two goals in quick succession so maybe we should look at that."
