Northampton Town player-coach Andy Holt admits there could be wholesale changes when they appoint a new manager.
Defender Holt, 33, is caretaker assistant to David Lee after Gary Johnson's departure this week.
Holt told BBC Radio Northampton: "Any new manager that comes in won't fancy a lot of the players the old boss signed.
"He'll want to put his own stamp on things. A lot of the players know they haven't done enough and have probably let their manager down."
The Cobblers face Shrewsbury on Saturday and Lee and Holt will take charge unless a manager is named before then.
Holt added: "Obviously it's up to the chairman now.
"If we are in charge at the weekend we'll try to get three points for the club and take it from there."
Holt, who arrived at Sixfields five years ago after spells with Oldham, Hull City and Wrexham, revealed the outgoing manager did speak to some members of his squad in the aftermath of his departure by mutual consent.
"Gary came in on Monday morning, spoke to a few of the players who were were and said his goodbyes," Holt said.
"It's been such a frustrating season. I believe we have three or four lads in the squad who could play at a higher level, no problem.
"But we just haven't had that consistency."
Former Cobblers boss Colin Calderwood, who was recently sacked by Hibernian, is one of those to be linked with the Sixfields role, and Holt believes he has strong credentials.
"The last time he was here he was very successful and got promotion before going on to bigger and better things," he said.
"But it's up to the chairman to decide who he thinks is right for the job."
