Swindon Town are looking to close the gap on the play-off zone to one point with victory at Carlisle today.
Although Peterborough remain in pole position to seal sixth spot in League One, they face their toughest assignment of the season at Wolves today.
Posh are four points clear of seventh-placed Swindon having played a game fewer, so Town manager Mark Cooper remains realistic about his side's chances.
"We know we've got to keep winning games," said Cooper. "There's no order that we have to win them in, but I think there's a certain amount of games we have to win to have any realistic chance of getting in the play-offs.
"If you start worrying about other teams it can then become a little bit of a muddle and what we've certainly not done over the last four games is worry about anybody else. We've just concentrated on ourselves.
"I'm not looking around. It's simple for us – we have to win as many games as we can.
"We can't look at anybody else because we can't affect their results. We just have to win as many as we can and if we do that then we'll see what happens."
Carlisle are battling to get out of the relegation zone and are one of four teams on 40 points, two of whom are just above the safety line.
Cooper added: "It's going to be a tough game because they're fighting for their lives. They've not conceded a lot of goals, but nor have we in the last few games.
"We know if we keep playing and fighting like we have done then we've got a realistic chance of doing something.
"I'm sure Carlisle will be desperate for three points and I'm sure they'll feel like they can get that against us," said Cooper.
"Defensively they've done very well. They've added Gary Madine to that, who is a very good striker, so we have to make sure we take care of him and his partners and make sure we pose a threat at the other end of the pitch as well.
"Fingers-crossed, with the way we've been defending, I'm sure we'll make it hard work for the strikers."
Swindon's options are increased by the return of midfielder Alex Pritchard from a three-match suspension, earned in the game against Bristol City.
Carlisle could give loan midfielder from Stoke Luke Dawson his debut, while Matty Robson, David Amoo and Pascal Chimbonda should all be fit as they chase a first win in eight. United have scored just three goals in that time.
