Mark Little's marauding run won the penalty that secured success in the Johnstone's Paint Trophy at London Road.
You could count the attacking runs made by full-back Mark Little against Chesterfield in the Johnstone's Paint Trophy success at Wembley Stadium on one hand, but one was all it took to secure success for Peterborough United.
Little's marauding run was ended in the box by Liam Cooper and Britt Assombalonga coolly notched up his 28th goal of a memorable campaign by converting from the penalty spot.
Little, who conducted his post-match interview complete with blue wig and flag, an outfit he wore at the play-off success over Huddersfield, said: 'It was a great day, we had a game plan to try and be professional and win the game and that is what we managed.
'It wasn't really the game for my attacking runs, we had got ourselves ahead in the game early on so I didn't have to provide the width, but we changed the formation and that allowed me to get forward and get into the box and create the the goal.
'Chesterfield piled on the pressure, but we stood up to the challenge. We made it difficult for ourselves by going down to 10-men and Joe will learn from that experience. Britt stuck the penalty away and we ran out winners.
'It is down to me now to sort a night for the lads. The manager is in a good mood at the minute so we have managed to squeeze a day off on Monday so it is down to me to get the party started. It won't be a major celebration though because we have a massive game on Wednesday against Colchester,' Little said.
