McAllister said: "I know what 40,000 of them sound like. I've been in front of them before and tonight again they were fantastic and the Leeds fans know that.
"That was for them tonight. The players would be first to admit that. It was a bit of a damp squib on Monday night at Elland Road, but I think the fans got the reaction they wanted.
"I'm very proud of the players and pleased for the players. Everything that's been put in front of them they've dealt with and I've not heard one murmur of complaint.
"We move on again. Slightly closer to the Championship. I don't want to be a killjoy, but nothing's been achieved yet. We've still got to go and try and win a game at Wembley."
