David Moyes has confirmed that James Vaughan could yet make Wembley.
But the Everton manager is warning that the striker must be ready before he's handed a first-team return.
Vaughan has just 68 minutes of reserve-team action under his belt since returning from knee surgery.
He told evertonTV earlier this week that it would be a dream to play at Wembley. But he also stressed he would be happy with whatever his manager decided was the best course of action.
Moyes said: "I think James looks as if he's a wee bit off it just yet.
"I don't want people to think there is an imminent return because he has a bit to do."
Everton Reserves face Manchester United next week, and Moyes suggested that if Vaughan fares well in that clash he could go on to play a part in the Wembley clash with the Red Devils' senior side.
"I'm hoping he can get involved in the last few games of the season," said Moyes.
"He's mad keen to be involved and to be around it.
"Maybe, if he gets another reserve game next week, and it pleases me, then he might be involved."
Vaughan's long-term injury has been one of several to beset Everton this term. The squad has, at times, been under real pressure and Moyes has been delighted with the way his players have responded.
In particular he picked out skipper Phil Neville.
"He has been one of the ones who has stuck with it," said Moyes. "He's hardly missed any football. I think Phil Jagielka is another one who's missed no games, no training. It's a long season and we know we have to rely on these players.
"We've had some outstanding 'steady' performers this year and you are right to mention Phil Neville."
