Brian laments late defeatBrian McDermott demanded that his team quickly develop a ruthless streak after losing 3-2 away to Wigan in injury time.
Jordi Gomez scored to give the hosts all three points, and it was a game Reading will certainly feel they should have taken something from.
Brian said, "We have to be more ruthless.
"At 90-odd minutes gone we had the ball in the corner and we have to take a point. Both teams had had opportunities but you have to take the point. Any point away is a decent one. We have to learn from that very quickly because this league is unforgiving. We have to see games through.
"The bottom line is that we've given a goal away with a minute to go which is crazy, just crazy and that was down to us. We have to take a draw at least, we were masters of our own downfall. We've got enough experience out there to know the momentum of the game."
With the scores at 1-1 Jay Tabb was fouled inside the box but Howard Webb failed to give a spot kick; a crucial moment in the game.
Brian said, "He missed a stonewall penalty, we've not had too many of those. That would have made it 2-1, it's very unfortunate but we have to move on quickly. I thought at the time it was a pen, and I've seen it again. I was surprised a referee of Howard Webb's calibre missed that one. If he doesn't give it he's got to book Jay for diving. I said to the linesman he's got to see that."
He continued, "In the dressing room we had a conversation and I said to the players the same thing, we have to be ruthless. Over the years we've scored many late goals but it's tough to stomach when it goes against you.
"At half time I thought we were going to win, but football is about results. We are really, really disapointed but we'll pick ourselves up quickly, we have no other choice."
