nobody is going to convince me that a penalty shootout with the nets being lifted at the back while the kicks are being taken is valid.
The penalty kicks were indeed not valid. I have no doubt that the evidence has been recorded along with the flare incident also perpetrated by their supporters in an attempt to disrupt the game (which they did to their ultimate benefit).
The nets were being clearly interfered with by a significant number of their fans before, during and after penalties were taken and it was clear to everyone that the referee failed to take any action.
Check out FA Laws of the game. Law 14 - The Penalty Kick
"The ball must be stationary on the penalty mark
and the goalposts, crossbar and goal net must not be moving".
However, according to the FA, the referees decision is always final so I don't think we will be appealing this..
