A Didier Drogba goal late in extra time was enough to secure victory for Chelsea over Manchester United in the first FA Cup final at the new Wembley.
Drogba produced a rare moment of brilliance in a game that failed to live up to expectations to complete a cup Double for the Blues.
With penalties looming, he played a one-two with Frank Lampard before poking the ball past Edwin van der Sar.
Ryan Giggs missed a good chance to win the game for United in normal time.
The 90,000 fans inside the stadium were treated to a fantastic pre-match build-up featuring some famous faces from Wembley's glorious past.
But aside from Drogba's late winner, the two best sides in the country produced a game that is unlikely to live long in the memory.
That is unlikely to bother Chelsea, who won the last FA Cup final at the old Wembley in 2000.
A cagey opening 20 minutes set the pace for a match that at times seemed more like the Community Shield than the first FA Cup final at an immaculate new stadium.
The first effort on target did not arrive until after the half-hour, with Paulo Ferreira venturing forward and slipping a pass in for Frank Lampard, who forced Van der Sar to make a smart low save.
That was about the extent of the first 45 minutes as both teams looked heavy-legged after a season in which they have each played over 60 games.
The pitch, which looked in fabulous condition at the start, began to cut up and so did not aid the footballing spectacle or the weary players.
Joe Cole looked one of the few players capable of livening things up before he was surprisingly replaced at half-time by Arjen Robben.
Paul Scholes picked out Giggs to volley just over the top as Sir Alex Ferguson's men showed the odd glimpse of the stylish side that dominated the Premiership.
The pace picked up slightly after the break, with United looking the more likely to score the new Wembley's first FA Cup final goal.
Wayne Rooney emerged from his first-half shell to bring a first save out of Petr Cech and tested Chelsea's back line with a couple of bursting runs.
At the other end, Drogba was largely contained by Rio Ferdinand and Nemanja Vidic, with the Premiership's top scorer limited to a curling free-kick that clipped the outside of the post during the 90 minutes.
Vidic could have settled the tie with the last touch of normal time but his glancing header from Giggs' inswinging free-kick was just too high.
Both sides had glorious chances to break the deadlock at the end of the first period of extra time.
Giggs somehow managed to pick out Cech with the goal at his mercy as he slid on to a Rooney cross and then Drogba headed into the side-netting from an equally promising position.
Salomon Kalou was agonisingly close to scoring before Drogba and Lampard exchanged passes and the Golden Boot winner capped a fabulous season with the most important goal of his campaign.
It prevented a third successive FA Cup final going to penalties and provided a memorable moment for the long-awaited return home to London for the competition.
Chelsea add the FA Cup to the League Cup, which they won earlier this season, and manager Jose Mourinho did his job prospects no harm by securing the one domestic trophy that was missing in his collection.
Man Utd: Van der Sar, Brown, Ferdinand, Vidic, Heinze, Fletcher (Smith 92), Scholes, Carrick (O'Shea 112), Ronaldo, Rooney, Giggs (Solskjaer 112). Subs Not Used: Kuszczak, Evra.
Booked: Scholes, Vidic, Smith.
Good to cotton on to the end there, Sean Knight-Phillips.
Bit of a deflection there.
It's Skoles who plays it through and Ceku comes in.
Fletcher. Oh, Rooney's offside! Offside flag up far side.
From the assistant Dave Bryan.
Now, Ronaldo.
Still loose, Carrick looking ahead, still Drogba.
Drogba shoots, that's the best moment so far.
Yeah, they're a bit more like it.
And in the moment there, Drogba turned and advanced.
Great run by Schur.
Trying to change the point of the attack.
Into Chelsea, Drogba in the centre.
Ain't say clear error.
Ball inside to Lampard!
That's more like it, isn't it?
Shot is by Wright-Phillips.
For Ronaldo.
Nothing here perhaps, no.
Good ball from Skoles, first time Ronaldo's when you decided for Rampard.
Lampard's shot.
I just wonder whether Van der Sar didn't see that until very, very late.
Offside here, Rooney.
It's a clever ball as well, this by Skoles.
Centre, so is Joe Cole.
Skoles challenged him.
Difficult ball for John Turry to deal with that.
I don't think we're going to have anything like a game here.
Rooney clearly upset.
And let's hope Jim Yarmthorne's on the way to recovery, Mark.
Yeah, most definitely.
It may not be now, Ned, he's got Giggs to his left.
And it's Rooney's shot, beaten out by...
And the offside flag is up.
Cheques say the return drive from Giggs, but the offside flag is up.
And it...
Past Wes Brown, fletches the other defender, Robben did ever so well.
But it's to no avail.
Is it me or could he have crossed it?
Wright-Phillips gets the cross in, Drogba won't reach that.
Now Drogba pulls away in the centre.
Oof.
Real Ferdinand did really well here.
Covered by Vidic.
This is Wes Brown.
Oh, and Essien, and a goal, and Ryan Giggs.
Goodness.
Essien was caught out there by Giggs.
Great ball by...
Rooney's in the centre here, Ronaldo crosses, away by Cherry.
To the right, Phillips, Drogba's in the centre.
And Drogba shoots!
Forward for Chelsea, towards Drogba.
Real tangled with Vidic, free kick.
Can he get it back to Lampard or Drogba?
Van der Sar in the way.
It's John Terry now, Wayne Rooney, Rooney!
Tried to go round Petr Cech.
Oh, what a thrilling run.
Great run, but also a great save by Cech.
Can he shake off McAleely?
It's Hans.
Into the wall.
Hounds lost out down here to Robben.
Soon made up for it, mind you.
Great tackle, that is.
Time, Rooney's in the centre square!
Oh, and Giggs just took a fraction too long,
and Michael Essien made the challenge.
Inside again, then outside.
Then tries a shot.
Away by Ferdinand.
Looking for Drogba, but it's harmless.
He's been driven back there.
He's up with Drogba here, but Drogba has taken it as far as he possibly can,
and he's thrown himself to the ground, it would seem to me.
Steve Bennett wasn't interested.
Although there's a Manchester United...
Oh, Van der Sar and Drogba have a little push.
Giggs.
Aldo and Brown with the two at the back.
He's gone out for a goal kick.
Yeah, they just seem to get in each other's way.
Away by Vidic, who's had an awesome game since McAleely.
Oh, a tumble on the far side.
Drogba is hovering here, Lampard's not far away from him.
Neither Giggs, Ainsley.
Wright-Phillips.
He's checked now, Robben is trying to get past Darren Fletcher.
Scholes to Giggs.
Oh, and Scholes was...
Oh, and there goes Lampard.
Oh, he's insisting he was impeded there by Vidic.
Fletcher's lost it to Lampard.
I just wondered, Joel, when it was on his left foot, Frank Lampard,
that he might have just...
Lampard hits the wall.
Giggs is in the centre, Ronaldo has gone for the near post.
I think if you're going to shoot in that particular part of the penalty area,
you've got to shoot across the goalkeeper.
This is Wright-Phillips.
He's in the centre, and Rooney's found a way through.
And it's still Rooney, and it's a corner.
Oh, and Drogba, Rooney's in the centre waiting.
That's Ronaldo's cross, and John Terry does that away.
Oh, and Vidic gets a touch on it.
That's about it to me.
Piece of the Premiership season.
First against second, Manchester United.
They were playing for extra time.
The big disappointment, of course, is that when you look at the two...
Taking the easy option physically, and I think that's a consequence of the season so far.
Both sides were very, very cautious right from the outset.
Now, normally...
Teams can regroup.
I think certainly we had a little bit of that.
Has anybody got any petrol left in the tank?
We're going to see now.
It's Manchester United start the first period, and that's towards Drogba.
I think we shall see Kalou in the middle.
Right, Phillips.
Oh, he'll be fresh at least.
Rooney's in the middle, coming near post now.
It's come off Essien, corner.
Forward was important.
Scholes.
Rooney wants it short.
Didn't get it.
I think John Terry.
Do you want me to watch John Terry?
Rooney's down the centre.
That's where it's going.
It's come off to Vidic.
Middle.
There's Alan Smith.
Smith, can he get a foot on it?
No, he can't.
In the middle, so it's Giggs!
Oh, how did he fail to score?
Or was it over the line?
Middle.
Peter Cech has grabbed it.
He slid in, Giggs, do you know?
And he just didn't make great contact with it.
How did he miss?
Still has the ball.
Lampard, he can't quite find it.
Side netting.
To time.
And then we're going to...
Rooney's shot.
He's headed it out to Wes Brown.
Then he stopped him coming inside.
There goes Rooney again.
Oh, and a mistake!
Oh, the flag stayed down,
and Michael Essien will be breathing a huge sigh of relief, Mark.
Yeah, and I tell you what, John...
Up to his left.
Salomon Kalou trips the goalkeeper and puts it wide!
Well, he did brilliantly in so far as getting him...
McAlealy again.
These are the two.
Alan Smith's brought him down,
and Smith has to be really careful here.
He's on the yellow card.
Mikel is up for substitutions.
Mikel played that forward to Drogba.
He's Drogba again!
And Chelsea have scored!
With five minutes to go and extra time,
Drogba has scored for Chelsea!
You might argue, John,
the best football of the game, Drog...
Jose Mourinho has pulled it off again.
