Aston Villa director General Krulak admits the club needs to send out a statement with their replacement for Martin O'Neill.
Krulak insists owner Randy Lerner will not be rushed into finding a replacement for O'Neill.
But he pledged that Lerner will be making public his thoughts on events during the last 48 hours and the future.
He said: "What I will say is that we recognise this is an important decision and one that needs to be done rather quickly but, equally important, in a manner that gets the right man.
"We do know how important this will be. No-one is thinking it will be easy.
"The reality is that we have four days before our first game and rushing out to get a manager is not the smart thing to do just to have someone on the sidelines."
Krulak added: "One of the sad things about this whole affair is that Martin left when he did.
"I agree that the club needs to come out with a statement - and they will.
"Likewise, Randy will have something to say."
