Guy Whittingham admitted he didn’t know whether a new Pompey boss would be in place for Doncaster on Saturday.
David Lampitt has pledged to take his time over deciding the man to replace Steve Cotterill.
The likes of Sean O’Driscoll, Iain Dowie, Mark Robins and Nigel Worthington have been linked with the Fratton Park hot seat.
As revealed by The News on Monday, O’Driscoll has applied for the position and reports have suggested the former Doncaster manager was in line for an interview today.
In the meantime, Whittingham and Stuart Gray have been put in charge indefinitely.
The duo oversaw another good Blues display last night, albeit ending in a 1-0 defeat against Ipswich.
It was their second match in charge following Saturday’s 2-0 success over Barnsley.
First-team coaches Whittingham and Gray are taking their roles on a day-by-day basis until a decision over the new manager is made.
Yet Whittingham conceded he was unsure whether that situation would change before the weekend clash with Doncaster.
He said: ‘We are looking at it day by day. That is all we have been told.
‘We are hoping to give the club enough time to get the right person in – and we are hoping the results are going to go the right way to allow us to do that.
‘It didn’t last night but the performances have been great.
‘We haven’t been told anything about the managerial job yet. We hope we can carry on. We’ve been enjoying it and the players are enjoying it at the moment.’
