Midfielder Adam Miller has overcome an ankle injury to be added to the 16 which featured in both legs of the semi-final win over Rochdale, so one player is facing the heartbreak of being left out at Wembley.
"It's a fully-fit squad so that's going to give me a little problem but we'll have to get over that," he said.
"Fingers crossed no-one does get injured, we've got two more training sessions, one on Thursday and one on Friday at Arsenal's training ground.
"If everyone does come through I don't see many changes but obviously the biggest problem is that someone is going to be upset because someone's got to be left out unfortunately.
"Of those 17 players, only 16 can be involved. That's going to be my hardest job on Saturday, telling that person that unfortunately they've not made the 16."
