Shell-shocked Reading manager Steve Coppell admitted his side had thrown away the platform that Dave Kitson's equaliser had given them in the 7-4 defeat at Portsmouth.
Kitson brilliantly levelled early in the second half after a rush of blood to head from David James but the Royals conceded almost instantly to leave Coppell bemused.
He said: 'I have never been involved in a game like that before. It's hard to remember anything like that either as a player or a manager.
'There were 11 goals in the game and there could have been more. There was no indication at half-time that it was going to explode into life like that.
'We dragged ourselves back into it with a five-minute flurry just before half-time to keep us in contact.
'Then we got ourselves in a position where we had a chance to go on and win the game. The penalty miss was crucial and their third goal was crucial. It seemed as though when either side attacked it was going to end up in the back of the net.'
