Harry Redknapp has tipped Pompey for League Two success this season.
The 68-year-old, who won the FA Cup as Blues boss in 2008 has given his backing to his former club.

On Redknapp’s daily kicca.com blog he said: ‘There have been big changes at Portsmouth with new manager Paul Cook coming in. Cooky knows the league well and has done a job in the lower leagues before.
‘Portsmouth are now debt free and I think they’ve got a great chance to get out of League Two and go on a run and I’d be absolutely delighted if they did.’
Redknapp also praised the support his old club receive, he said: ‘Not a lot of people know this but when you live there you support Pompey, you see very few Man Utd shirts or people wearing the tops of the ‘big clubs’.
‘You especially don’t see any Southampton shirts, that would be more trouble than it’s worth!
‘I, Jim Smith and Kevin Bond had a great time there and would love it if they do well.’
Pompey have made nine new signings this summer, including Gary Roberts and Adam McGurk, who have achieved promotion before.
Luton Town also look in a strong position this season.
John Still’s men produced an impressive performance when they won 5-2 at Privett Park on Monday night.
Redknapp added: ‘They (Pompey) and Luton, under my old pal John Still, are the teams to beat in the league. Those two will take some stopping.’
