Shrewsbury manager Graham Turner was annoyed at the way his side defended set-plays in their 3-0 defeat at Leyton Orient.
It took Orient 56 minutes to break down a resilient opposition, but once David Mooney had got the breakthrough with a header, the home side dominated. Irishman Mooney added his second of the game with another header after 63 minutes before talented winger Moses Odubajo added a third in added time.
"We needed to stay strong, we knew they were a threat from set-plays, that they were very direct and we would have to deal with all that," Turner said.
"We did it for 45 minutes, in fact we did it very well and also had one or two chances and I thought their keeper made several good saves. For 20 minutes before half-time, we really took the game to them.
"The first goal though settled them down, it settled the crowd down and it was a pivotal in the game.
"That gave them momentum and after that they got on the front foot a bit more. The really annoying thing for me is that we went through set-plays in training and again at our hotel, but we got caught from two of them.
"You can't afford to do that, we knew what was coming and you have to be able to deal with it. "As a manager, you think that a three-nil scoreline is harsh and wasn't a true reflection of the entire 90 minutes, but we have to be a bit more aggressive in their box if we are going to get goals.
"The same at the other end, we've got to be able to deal with a long throw or a second ball from a long throw and we have to defend the back post better than we did."
