MK Dons booked a place at Wembley with a nerve-shredding Johnstone's Paint Trophy penalty shootout win over League 1 leaders Swansea at stadiummk.

Substitute Drewe Broughton buried the winning kick to maintain the Dons' incredible run in shootouts this season, securing a 5-4 win after Willy Gueret had broken his old club's hearts - crucially saving from hotshot Jason Scotland.

Scotland had already beaten the former Swans stopper with a first-half spot-kick that levelled the tie after Andy Robinson had been fouled by Keith Andrews in the area.

But Gueret came out on top when it truly mattered, plunging low to his left to give his ice-cool team-mates the chance to win it.

Win it they did, with Broughton, who only returned from a loan spell at Wrexham 48 hours before, slotting the Dons' 15th successful shootout attempt out of 15 this term.

Willy Gueret saves Jason Scotland's penalty in the shootout.

It sparked wild celebrations inside stadiummk, with the crowd spilling onto the pitch to congratulate their heroic team, who will now face either Morecambe or Grimsby in the final on March 30.

How Ince's players deserved it after running themselves into the ground for the third time in six days against a Swans team packed full of international talent.

In Robinson, the Swans have a player capable of winning a match in an instant and, having tormented Drissa Diallo in the opening stages, it came as no surprise when his trickery led to the penalty.

Slipping into the box from the left flank as he loves to do, Robinson was half a second too quick for Andrews, who sent the winger sprawling as he tried to nudge the ball away.

Scotland shut out the boos of the Dons supporters to level up the tie, cancelling out Jemal Johnson's goal at the Liberty Stadium with his 20th goal of the season.

Jemal Johnson looks to add to his first leg goal.

Those who feared the worst were given a jolt to the contrary as the diehard Dons came out fighting.

They responded brilliantly, Andrews beginning to dictate play and crunch into brilliant tackles with any Swansea player that tried to stop him.

Kevin Gallen saw a shot well blocked by Alan Tate after good work from Colin Cameron and Johnson should have done better with a volleyed chance after a great cross from Diallo.

With the tie in the balance, the Dons looked determined to regain the initiative and when Andrews made a clever break into the box from the right, his cutback was only a whisker away from taking it.

But despite a couple of routine catches, Dorus de Vries in the Swansea goal hadn't been truly worked before the break.

Likewise, Gueret had had little to do at his end but had to be on his toes early in the second half to deny Febian Brandy, who had raced in behind onto Scotland's pass.

Lloyd Dyer takes on the Swansea defence.

De Vries was then duly worked in kind when Gallen got some part of his anatomy onto a free-kick from the outstanding Dean Lewington.

The full-back next contribution, a towering header over Thomas Butler, should have brought the equaliser.

Johnson raced onto it with Garry Monk desperately trying to keep up, but chose to pass instead of shoot as he approached the box.

Gallen stepped over it allowing Lloyd Dyer space, but his touch and shot took the pace out of the attack and de Vries needed only to make a simple save.

Dyer brought a better save from the Dutch 'keeper moments later from a carbon copy attack - firing goalwards from Alan Navarro's pass after Gallen had dummied Lewington's pass.

Colin Cameron tumbles under Andy Robinson's challenge.

Gallen was developing a taste for it and had appeals for a penalty turned down on 68 minutes, Monk's challenge deemed fair as Gallen prepared to pull the trigger.

But Swansea have not built a 14-point lead in the division above for no reason and they kept coming in a pulsating second half.

Robinson was blocked brilliantly by Sean O'Hanlon as he tried to convert Scotland's cross and, from Robinson's resulting corner, substitute Shaun MacDonald volleyed horribly over.

Broughton came close to winning it with his first touch after replacing the injured Diallo, but the big striker couldn't get round Monk as he tried to force home Johnson's cross with five minutes to go.

If that was a chance, a better one fell the way of Gallen in injury time but the striker couldn't divert Jude Stirling's pacy delivery on target.

Kevin Gallen scored a crucial penalty after Scotland had missed.

To penalties it went where the Dons are developing a specialist reputation.

Scotland's denial with the scores at 2-2 left Gallen to ram home the initiative and after Andrews, Lloyd Dyer and Stirling had also been successful, Broughton's moment came.

Incredibly, the journeyman striker could return to Wrexham for tomorrow's League 2 game against Peterborough but, for tonight, he's the man that sent the Dons to Wembley.
