Reading manager Brian McDermott was relieved to reach the third round of the Capital One Cup following a frenzied 3-2 victory over Peterborough.
The Madejski Stadium was treated to four goals in seven minutes with the npower visitors taking the lead twice through Paul Taylor and Lee Tomlin.
Pavel Pogrebnyak and Chris Gunter put Reading back on level terms before Nathaniel Knight-Percival nodded home an own goal in the 38th minute that proved to be the winner.
McDermott admitted his side's defending left much to be desired.
"Open's a good way to describe that game.....kamikaze if you like," McDermott said.
"It's fair to say that without the ball we didn't do as well as we normally do. With the ball at times we were very good.
"You have to give Peterborough credit because they had good players who pass the ball. They caused us problems.
"We know that as a team we need to be better with the ball, but we're pleased to be in the next round."
Peterborough have lost all four matches this season and manager Darren Ferguson insists they must stop the rot.
"From an attacking point of view we played some good stuff. We caused them problems," he said.
"But the goals we conceded were really poor. We should have entered half-time ahead, instead we were behind.
"We were unfortunate not to get something out of the game. It's a disappointing result and the goals we conceded were disappointing.
"It's another game lost, but I don't want us to be known as a good footballing team that loses games.
"We've got to start winning games - that's what it's about. We can't concede goals like that."
Ferguson denied knowledge of any bids from Ipswich for Paul Taylor and George Boyd.
