Nigel Adkins admitted his was very frustrated with Saturday's stalemate at Oldham Athletic.
Matt Done cancelled out Danny Philliskirk's early opener for the Latics on the half hour and in the second-half the visitors missed two gilt edgde chances to take all three points.
Reflecting on a point in Lancashire, the Gaffer commented: "We should have won the game and we haven't.
"We gave away a poor goal, through an individual mistake and in the first-half we didn't win enough of the one-on-one battles across the pitch.
"But in the second-half we created enough chances to win the game and both Billy (Sharp) and Stefan Scougall should be scoring with their efforts.
"They had a man sent off when the game was just opening up a bit, but whether they say deeper or not we need to be winning these types of games."
Adkins continued: "We are really disappointed not to take the points, but full credit to Oldham who worked tremendously hard.
"You have to mark your man from a set-pieces, it's a simple job, we have been drumming into the players all week about the importance of keeping clean sheets.
"We have missed a chance to start a big week with a win, we have got a run of fixtures coming up where we could pick up a lot points quickly and we should have been talking about three here."
