Strengths: Would make quick, sweeping changes and is good with the media.
Weaknesses: Has been out of the game for nearly three years and his last job, at Newcastle, was not a success.
Fans' reaction: Mixed – was on a downward spiral before he left Blackburn for Newcastle in 2004 but remembered for League Cup win in 2002.
Playing honours: Five league and three European Cup wins with Liverpool.
Managerial honours: Scottish league winner three times with Rangers, won the FA Cup with Liverpool in 1992, the First Division with Blackburn in 2001 and the League Cup in 2002.
Sam AllardyceAge 54
Strengths: Seen as an experienced hand and has been through plenty of relegation fights in the past. Would bring solidity and organisation.
Weaknesses: Desire for a large backroom staff may be seen as a negative and has also been criticised about his playing style.
Fans' reaction: They were far from impressed at the prospect of him joining in the summer, but would be a lot happier to have him on board now.
Playing honours: Second Division title with Blackpool in 1977/78.
Managerial honours: Fourth Division title 1997-98 with Notts County, Carling Cup runner-up in 2003-04 with Bolton.
Alan CurbishleyAge 51
Strengths: Would also be seen as a steady appointment with numerous successful scraps against relegation, with both Charlton and West Ham.
Weaknesses: Would not have the funds that he enjoyed at West Ham and ongoing legal action with the Upton Park club may scupper any chance of taking over at Rovers.
Fans' reaction: The fans would not be overwhelmed but would respect his proven track record in the Premier League.
Playing honours: England Under-21 international.
Managerial honours: Won promotion to the Premier League with Charlton as champions of the old First Division in 2000.
Owen CoyleAge 42
Strengths: The Burnley manager is seen as one of the brightest young talents outside the Premier League and has turned the Carling Cup semi-finalists into promotion hopefuls.
Weaknesses: Considering Blackburn's perilous position, his lack of experience would count against him. Has never dealt with players of the stature of Roque Santa Cruz and Benni McCarthy.
Fans' reaction: Would be wary of the appointment of someone with no top-flight managerial experience at this time, particularly from a bitter rival.
Playing honours: Republic of Ireland international.
