Harry Redknapp has been installed as the early joint-favourite to succeed Andy Awford as Pompey manager.
Redknapp, who guided the Blues to FA Cup glory in 2008 and brought the old division one title to Fratton Park in 2002/03, is the 5/1 front-runner along with Gary Waddock, according to Sky Bet.
The former Spurs boss is out of work after leaving QPR at the start of February.
Awfs’ former assistant manager, Waddock will take charge of Pompey for the remainder of the season.
Meanwhile, out-of-work duo Ian Holloway (6/1) and Darren Ferguson (8/1) are next on the list, followed by Neil Warnock at 9/1.
Former Saints striker and Accrington boss James Beattie is a surprise 10/1 to be placed in the Pompey hot seat.
He is joined at tens by Uwe Rosler and Paul Cook - ahead of Danny Wilson (12/1), Paul Hardyman (16/1), Nigel Worthington (16/1), Gianfranco Zola (25/1) and Gus Poyet (33/1).
Another surprise name on the list is Rocks manager Jamie Howell, who has odds of 40/1.
