Ipswich Town boss Paul Jewell has said he has concerns over his side's mental strength after the 3-2 loss to Reading.
It was the second game running Town had dropped points in injury time, following defeat by the same scoreline to Nottingham Forest a week earlier.
"We're not strong enough. We're not mentally tough enough to see games out," Jewell told BBC Radio Suffolk.
"We should have had the game sewn up last week. The team's lacking in cohesion and confidence."
Ipswich are now one point off the Championship drop zone, having lost their last five games, and have been on the end of 3-2 reverses in their most recent three outings.
Saturday's defeat saw Jewell's side go into added time 2-1 ahead, only to somehow end up losers.
"It's horrible. It's a sickening feeling," said the former Wigan boss. "The nature of how we threw victory away was disappointing.
"The way you get over that is by winning matches and if we could have got three points it would have done a lot for our confidence."
Jewell opted to face the Royals with a changed formation, leaving out midfielders Jimmy Bullard and Lee Bowyer in favour of the width supplied by Josh Carson and Jay Emmanuel-Thomas.
"The diamond system has worked well for us a lot but the last few games it hasn't," explained Jewell.
"I just thought Jimmy and Bowyer have been a little bit jaded. We needed to try and get a bit of width.
"At times it was OK but I'm not kidding myself - even if we had won 2-1 it would have been a scrappy win.
"But we need a scrappy win from somewhere."
