Forget Sir Alex, this was a day for Fergie junior’s Wembley wizards

this final against League Two opposition, but instead he delivered his fourth tangible triumph as Posh boss - double that of the next-most successful manager in the club’s Football League history.

No wonder then that he soon became weary of questions about his dad, mum, wife and dog when all he wanted to do was praise his chairman and his opposition before joining in the Posh celebrations.

“The chairman has stood by me when others wanted me out,” Ferguson, who joins a Posh legend and Barry Fry as managers who have led the club to a Wembley triumph, stated.

“And I hope it’s because he realises I am the best man to steer Posh through the playoffs.

“Chesterfield are an excellent side and they will be in League One next season, but I hope we aren’t there with them.”

Posh and Ferguson hope that the club put their 100 per cent Wembley record on the line once more at the end of May.

It’s now three wins from three visits to the national stadium now and it’s fair to say that Posh haven’t played particularly well in any of the games.

A scorching hot day in 1992 restricted the talents on show and in 2000 Posh were poor in heavy rain until pinching a winning goal 20 minutes from time.

Posh didn’t take that long to get going on this occasion - a l t h o ug h S h au n Br i s l e y should have conceded a penalty for a fourth-minute trip - but between their first goal in the sixth minute and their second goal seven minutes before the interval, they were distinctly second-best to a slickpassing Chesterfield side.

But somehow the League Two promotion contenders contrived to submit two entries into a ‘miss of the season’ competition as Sam Morsy shinned the ball wide from eight yards to ruin excellent work fromTandayi Darikwa and skipper Ian Evatt headed the ball straight at Bobby Olejnik when it looked impossible not to score.

Straight after Evatt’s miss, Brisley rose majestically to head home a Danny Swanson corner and the haplass Chesterfield skipper had also been off the field for treatment when another Brisley header, this time from a Grant McCann corner, lead to Josh McQuoid’s early tap-in.

They were most unlikely goalscorers as McQuoid hadn’t netted in the previous 14 months and Brisley had played 71 games for Posh without without scoring.

On the other hand Britt Assombalonga has scored 28 times in just eight months. His penalty 12 minutes from time followed a fabulous burst into the Chesterfield penalty area by Mark Little which was rudely interrupted by Liam Cooper.

It was a crucial moment as ‘The Spireites’ had pulled a goal back eight minutes after the re-start through Eoin Doyle and Posh midfielder Joe Newell had shown some rare aggression to receive a red card for probably the softest act of violent conduct in the history of football.

Momentum had switched strongly to Chesterfield at that point, but - and this might be a bigger embarrassment for Newell than his dismissal - Posh looked more solid with 10 men and the late introduction of speedy sub Lloyd Isgrove meant they looked the more likely to score further goals.

Isgrove’s burst through a toiling defence to force a fine save from Tommy Lee was the last interesting act of the contest before the presentation of the first cup Posh have ever won that didn’t involve a final against the likes of Corby or Kettering.
