Paul Sturrock said: "I am 52 years old and have been there, done that and got the t-shirt.
"Pressure is part of being a football manager and is something you have to accept. Everyone in football is judged on results and we haven't been getting them.
"We could have done without a lot of other teams down there picking up good results as well, but the challenge now is to take the momentum forward and build on this success.
"We have brought a lot of quality players into the club and tried all sorts of different systems, but I decided to go back to being horrible and effective, and thankfully it worked."
Posh boss Darren Ferguson admitted: "It was a game we were expected to win and a big disappointment that we didn't manage to do that.
"We had six good chances inside the six-yard box but only took one of them, while we gave away two bad goals at the other end. Anyone who has seen us regularly this season knows that those things have been our problems.
"We have won one game out of 10 and that is obviously nowhere near good enough. We have a big challenge ahead of us - the sort we haven't faced before during my time here - and we need everyone to stick together, including the punters."
