Assistant manager Glynn Snodin knows the North End must concentrate on their own game more than ever at Loftus Road on Saturday.
Queens Park Rangers saw a change in manager during the week, with Chris Ramsey being replaced by interim boss Neil Warnock, and Snodin admits that the team's preparation must be on themselves ahead of the game.
"Three or four hours earlier [before the announcement] I was watching their game against Brentford that I had recorded, and I was taking notes down on that and now Chris has gone bless him, another causality, and everything will change again now.
"We could put presentations on for the lads to watch but then it could be completely different, even the set plays, so it is going to be different now but all we can do is concentrate on ourselves.
"I think Neil will know the players, as he's been there and watches from upstairs so I think he will have a good idea on who he wants to play and what system he wants to play.
"We all know Neil's philosophy, we know he's a born winner, we know how he sets his teams up and I wouldn't think it would be too different to be fair. He knows the Championship well, so you'd probably be looking at a 4-4-2, up and at it and organised and disciplined."
Speaking of PNE's current form, Snodin continued: "To keep cleansheets is a great achievement in this league at the moment, it's fantastic, and let's hope that continues. Credit to the lads who go out there and have done it week in, week out.
"It would be a great achievement to go into the break unbeaten, that form happens when you're in the top four or six, not in the bottom four, so to do what they've done to respond with this run is magnificent.
