Bookmakers have made former Pompey star Tim Sherwood the favourite to take over the manager’s seat at Aston Villa.
Villa are starting their search for a new manager following last’s departure of Paul Lambert.
The Scot paid the price for the club’s plunge into the Barclays Premier League relegation zone, despite signing a contract extension after a good start to the season in September.
Former Tottenham boss Sherwood has been named favourite for the job by several bookies, with current Real Madrid assistant Paul Clement and United States head coach Jurgen Klinsmann also said to be in the frame to replace Lambert, as owner Randy Lerner begins the search for a new boss.
Sherwood played 30 times for Pompey in 2003-04, scoring one goal, before moving to Coventry City.
Meanwhile, former striker Peter Withe has offered to help out Villa as they seek the right candidate to lift them out of danger.
Withe, who scored Villa’s winner in the 1982 European Cup final against Bayern Munich and has had a varied career in management including spells with Wimbledon, Thailand and Indonesia, said: “I will help them for nothing.
“I think they’ve got to get someone who has a feel for the club and can bring the fans back and also just inspire the players a little bit.’’
