Petreborough United defender Gabriel Zakuani says the team have a new-found sense of freedom under caretaker boss Dave Robertson.
DR Congo international Zakuani marked his return to the side with a goal as they beat Bradford in their first game since the departure of Darren Ferguson.
"He has relieved a lot of pressure," Zakuani told BBC Radio Cambridgeshire.
"He just wants us to express ourselves a little bit more. It feels like a few shackles have been taken off."
The victory moved Posh up to 10th in the League One table and to within four points of a play-off place.
Zakuani, who featured four times for DR Congo as they finished third at the recent Africa Cup of Nations, has backed academy manager Robertson to take permanent charge of the League One side.
"I've known Dave a long time now - he is Peterborough through and through. He has done great work with youth lads and done well on a limited budget.
"He has come in and made a big impression on the players and all the players are behind him. As long as he is here we will play for him."
The 29-year-old also praised the return of former team-mate Grant McCann as Robertson's assistant.
"Grant is a legend at this club, we respect him a lot and he is someone we want to play for," said the former Fulham and Leyton Orient man. "He will be a very good coach."
Meanwhile, 17-year-old goalkeeper Dion-Curtis Henry has signed a two-and-a-half-year professional contract with Peterborough.
