SIR Alex Ferguson today vowed to stick with his Manchester United youngsters for their Carling Cup Final appearance at the beginning of March.

United booked a Wembley date - almost certainly with Tottenham - with a 4-3 aggregate win over Derby.

Darron Gibson, John O'Shea and Danny Welbeck have been among the unsung heroes who have been regular performers in the competition this term.

And they can all bank on retaining their spots as United compete in their 14th domestic final of Ferguson's reign.

"They will all play in the final," said Ferguson. "They deserve to. It is always a great occasion at Wembley but the only way you can really enjoy it is by winning."

However, of more immediate concern will be finding a team to play Tottenham in Saturday's FA Cup fourth-round tie at Old Trafford.

With Rio Ferdinand, Wes Brown and Patrice Evra already ruled out, the Red Devils could not afford to lose Rafael with a torn hamstring that will keep him out for at least a month, and Jonny Evans who limped through the latter stages.

In addition, Anderson was taken for X-rays on the ankle injury that forced him to be stretchered off after the final whistle, while Nani, Gary Neville and Ryan Giggs all failed to complete the full 90 minutes.

"There are probably six or seven of them who have picked up injuries," confirmed Ferguson.

Darren Fletcher is almost certain to be called on as a makeshift right-back, while Fabio might be handed his senior debut against Spurs if Neville does not make it.

Nani, O'Shea and Carlos Tevez scored before half-time for United and, although Giles Barnes found the net twice for Derby, Cristiano Ronaldo split them with a penalty of his own.
