MILLWALL boss Ian Holloway was left feeling "completely and utterly sick to the core" by Tuesday's 3-2 defeat to Reading.
Holloway felt the Lions' display at the Madejski Stadium was one of the best of his tenure at The Den so far.
The visitors bounced back after going 2-0 down inside the opening 15 minutes, with goals from Ricardo Fuller and Mark Beevers levelling the scores.
But Simon Cox grabbed his second of the game in the 86th minute to steal the points.
And Holloway said: "I feel completely and utterly sick to my core.
"Sometimes as a manager you know when you don't deserve anything but anyone watching that would say we were worth at least a point.
"My wife summed it up the other day when we were playing golf. She said, very simply, golf can be a cruel, cruel game. Football can be as well sometimes.
"If we deserved to lose that game, then there's no justice – and sometimes there's no justice in football.
"In my time here, that is as good a performance as I've seen. I'm kicking myself because that's no points out of two games and we're slipping but we didn't deserve to slip.
"That's as good as any team of mine has played in a long, long time. We passed it and we moved it. We regained the initiative.
"That is as good as we've played all season apart from a couple of lapses."
Cox opened the scoring with a low 30-yard drive into the bottom corner after Reading broke from a corner and the striker won it with a close-range header from a set piece.
Sandwiched inbetween Cox's brace was Nick Blackman's penalty.
Holloway said: "We have to defend our own corner a bit better than that when they broke for the first goal.
"Cox beat two of our players and smashed it in the bottom corner – it was a fantastic bit of play.
"But we spoke about that situation on Monday because we had a throw in at Ipswich which they scored from, so I left two back and they both tried to win it.
"All we had to do was hold them up until the cavalry come back. We got it wrong and Cox scored a great goal.
"The referee has then given a penalty which I didn't think was a penalty – but it was because he gave it.
"We went a goal down against the run of play. I thought we started really brightly and then all of a sudden we're 2-0 down.
"But the lads managed to get their minds back in the game. I thought we were terrific, right until we let a goal in from another set play.
"We gained the momentum and we deserved the momentum.
"We created wonderful scoring opportunities against a team that have been doing well, but unfortunately we have to defend a bit better than that.
"We made a couple of errors and we've been punished. We've had 18 shots, they had nine and only three of theirs were on target – but they've scored all three of them."
