Skipper Paul Robinson's first-half goal in the League One play-off final fired the Lions back to the Championship after a four-year absence.

Millwall, beaten in their previous five play-off campaigns, also needed a helping hand from the much-maligned Wembley turf as a nasty bobble denied Swindon's Charlie Austin the chance to equalise.

But the Lions held on for the win and, having lost last year's final and finished in third place this term, deservedly followed Norwich and Leeds into the second tier.

Victory also marked an upturn in fortunes for Jackett, who was in charge of 2006 losing finalists Swansea and saw the Lions narrowly beaten by Scunthorpe in last season's showpiece.

"It's nice," Jackett said. "It's the sixth time for Millwall in the play-offs and for me as a manager it's my third time, and it certainly beats losing.

"The club had come a long way last year and it was so disappointing at the end.

"So we built on that anger and I'm pleased to say the players have seen it through."

Robinson's goal came six minutes before half-time, the defender poking home from six yards after Swindon failed to deal with Danny Schofield's corner.

Millwall had the ball in the net earlier in the first half via the head of Swindon defender Kevin Amankwaah, but his blushes were spared by an offside flag.

Swindon's big opportunity to level fell to Austin, the prolific striker plucked from non-league Poole Town back in October.

The 20-year-old was gifted a clear run on goal by Robinson's poor header in the 70th minute but, as he shaped to shoot, the ball bounced up and his shinned effort drifted wide.

"It's maybe the bit of fortune you need," Jackett admitted.

As south London prepared for a long-awaited promotion party, Swindon boss Danny Wilson was left to reflect on what might have been.

"The game hinged on two moments, a missed header from us at the corner and a bobble for Charlie," he said.

"I'd have put my house on him but what can you do when the ball bobbles up like that? You can't blame the boy.

"He's inconsolable, but his goals got us here today. We wouldn't criticise him even if it wasn't a bobble. Maybe it's fate, I don't know.

"It's absolute devastation in the dressing room but they can be very proud of what they have done this season."

Town chairman Andrew Fitton was even considering his position at the club following the disappointment of defeat.

"I need to think about the way the club is run and what happens in the future," he said.
