Madden, along with first team coach Steve Macauley, took charge of preparations for Saturday's visit of Southend following Micky Mellon's shock exit last weekend.
The 40-year-old Mellon was dismissed following their FA Cup defeat to Aldershot but Madden says the players need to remain professional.
"The lads are still getting over the weekend's developments but they have to be professional," he told the club's official website.
"They know Steve and I well so to that extent nothing's changed. Tuesday we split the group up and combined a bit of fun with some serious work in the gym and on the artificial surface at Fylde Rugby Club.
"It's out of my hands so we just have to get on with the preparation for Saturday.
"The crazy thing is that if we win against Southend and other results go our way we are just outside the automatic places, lose and it can look quite different again.
"It's a very tight league and we need a performance and a win on Saturday."
