Iain Moody's resignation could further damage Crystal Palace's bid for Premier League stability, according to the club's caretaker manager Keith Millen.
Moody resigned as Palace's sporting director on Thursday, amid allegations of sexism and homophobia against him and Malky Mackay during their time at Cardiff.
The Football Association has confirmed an investigation into the dossier of allegations submitted to the governing body by Cardiff bosses.
Mackay was all set to be appointed Tony Pulis' successor at Palace, until news of the FA investigation broke.
Millen admitted Moody's departure could unsettle Palace still further, as the club seeks a replacement for Pulis, who walked out on the eve of the season after rowing with the board over transfers.
"Iain was brought in to do a job to recruit and scout players, and Iain was experienced at that job," said Millen, admitting Moody's departure leaves a chasm at Selhurst Park.
"The chairman will now have to look at that situation, to see whether he wants to bring someone in."
Palace's managerial search is back to square one after the FA investigation ruled Mackay out of the running, with Chris Hughton now among the new contenders.
Millen admitted Mackay's managerial style would have suited the Selhurst Park club perfectly.
"Malky has got a good track record: I think he's used to working with players that want to work hard for him," said Millen, who will take charge of Saturday's home Premier League clash with West Ham.
"The way he set his teams up they were successful and organised.
"And that's our DNA as a club and a squad, to make sure we work hard for each other, there's a great togetherness in the group.
"That really suits the type of players we've got here.
"Whoever comes in will need to work within those boundaries.
"Each day something's unfolded, something's come out, so it's been difficult.
"I had a brief chat with the players today about staying focused, and the lads have been fine, they are resilient as a group."
Palace will chase their first points of the season on Saturday after losing out 2-1 at Arsenal on the opening weekend of the new Premier League season.
Millen rejected claims Palace's extended search for a new boss will damage their Premier League credentials.
Millen took the assistant manager role at home town club Palace when Ian Holloway took control in November 2012.
The 47-year-old took temporary charge when Holloway was sacked a year later, then stayed on at Selhurst Park under Pulis.
Still keen on securing the manager's job full-time, Millen said only immediate results will sway the board's thinking in his favour.
"I don't think all this weakens us no, we've got the same group of players," he said.
"They trust me and the way we set things up.
"The set-up is here, so there are no excuses.
"We'll continue setting up the team until we're told otherwise.
"If we get some results the chairman may then decide I tick enough boxes to take the team forward."
Millen said he will continue to hold regular meetings with co-chairman Steve Parish over transfer targets, mindful of the fast-approaching September 1 deadline.
"That's the tricky part," said Millen on planning transfers without recruitment specialist Moody.
"We speak about players all the time: and we need to look at the kind of players that will suit our style of play.
"If we can come up with some names, then at least whoever takes over, we can at least say, this is what we feel we need.
"So we'll keep doing that, there will be a meeting this afternoon and then there will be more discussions on that topic."
