Rivals could have to battle for leading candidates like Keith Hill, Russell Slade and Neil Redfearn.
After Paul Lambert opted against extending his stay at Ewood Park, club secretary Ian Silvester has been working on the shortlist to replace him, and HITC understands that it contains former Rovers player Hill - who is widely regarded as one of the best young managers in the Football League, following some great work at Rochdale.
Former Leeds and Rotherham boss Neil Redfearn and more surprisingly one time Bolton hero Alan Stubbs - currently the boss at Hibernian and Slade - who was in charge of Cardiff - are the others also in contention.
Slade has moved upstairs at Cardiff, with Paul Trollope taking the head coach role, and it is understood the former Leyton Orient chief would prefer to be back at the helm of a side.
Sources close to the situation have exclusively told HITC Sport: "They know who they want to talk to and that will happen early next week and a deal should be done with a week or so."
North East sources have linked Hartlepool United boss Craig Hignett to the role, but it is understood his lack of experience has ruled him out of the running despite his impressive work in keeping the Teesside club in League Two.
Charlton are looking to rebuild after losing following their relegation to League One and the departure of Jose Riga, but they want to bounce back to the Championship at the first-time of asking.
Slade and Hill are both thought to be very high on their list of targets, as the South London club look to make an appointment by the end of the month.
HITC Sport also understands that one-time Charlton star Redfearn is also keen to talk to the club and it is believed he could be the leading candidate.
