FA CUP: Crystal Palace 2 Aston Villa 2

A replay a week on Wednesday will pay off another chunk of Palace's 30m debts and the way Neil Warnock's side scrapped no one should write off their chances of reaching the quarter-finals just yet.

But how cruel football can be.

It looked as if Darren Ambrose had given Palace the cup shock they craved when he fired the strike of his life past goalkeeper Brad Friedel from more than 30 yards.

The Palace faithful sang 'We're going to Wembley' and former Sheffield United manager Warnock was a picture of animation on the touchline.

The Championship side's optimism looked well-founded as Villa struggled to conjure an attacking threat in a lacklustre second half.

But then came Petrov's goal three minutes from time which leaves Palace hoping they can cash in on another televised encounter to bring in a further 250,000.

To say Palace were up against it in this tie is an understatement.

The club went into administration a fortnight ago with those staggering debts.

The players' futures are uncertain, manager Warnock does not know if he will be in a job from one week to the next, and the canteen lady has not been paid for two months.

There have been lots of beans and toast on the menu at the club's Beckenham training ground but you cannot fault the spirit in the side.

For long periods in an entertaining, at times pulsating cup tie, they gave as good as they got. As good as Warnock had promised, in fact, when he predicted they would not go down without the mother of all scraps.

Ambrose up front was a constant threat. Neil Danns was also a menace and while Danny Butterfield could not conjure up the six-minute hat-trick which dispatched Wolves in the previous round he did epitomise the astonishing work-rate shown by the south London team.

But give Villa credit. Martin O'Neill paid Palace the respect of fielding his strongest side with Emile Heskey up front and Stewart Downing and James Milner in midfield, and Villa dominated much of the possession.

But it was Palace who took the lead and when it came after 24 minutes it arrived from an unlikely source.

Austrian defender Johnny Ertl had never scored for Palace in two years at the club but maybe he has never had a better delivery come his way, a corner swung in by Ambrose which homed in on Ertl's bald pate.

A quick flick of the neck and the ball flew past goalkeeper Friedel and a cup upset appeared to be on, even if the goal did come against the run of play.

If Danns's crisp shot had also found its way past Friedel then Villa would have been in trouble.

As it was Villa composed themselves and announced their intention to scrap just as hard as their Championship rivals.

When the equaliser came it had the mark of England quality. It was also a carbon-copy of the Palace goal.

This time it was Downing who threw in an inswinging delivery from the right and Villa defender James Collins rose above everyone to head home from inside the six-yard box.

It was no more than Villa deserved, although the last action of the first half saw Friedel scrambling away a 25-yard thunderbolt of a free-kick from Ambrose.

Villa should have taken note, especially when Ambrose lined up another in he 69th minute.

This one was further out, some 30 yards or more, but the strike was even better this time, arrow straight, and it was past the despairing dive of Friedel in the blink of an eye.

What a wonderful goal. What a way to win a football match – except it did not because Petrov swooped to get Villa out of jail.
