Referee got it wrong. Penalty should have been retaken. Defender had encroached as well. Absolute bell end.

Looking at the replay, it wasn't just a defender - it was at least half a dozen of them. And one of those was further into the area than Kayembe.
Just seen the Luton result - when we were scoring our last minute equaliser, they were doing the same
According to the commentators it was disallowed because Kayembe's fingers were offside as he leaned forward If you cannot score with your hand or lower arm then you cannot be offside from your hand or lower arm
I was close to a monitor in the stadium and Kayembe encroachment was miniscule if at all. I don't know if defenders encroached or not. Anyone seen it back? Also, why Louza when Kayembe took the last one?
Need that sort of thing to go for you if nothing else is working. Stick for Javi (some saying he has to go even!) and 442 may not work too well but we did miss some good chances and well whoever plays in defence doesn't make much difference.
