Billy Davies surveyed problem-hit Pompey and insisted: I have no sympathy.
The Blues head to Nottingham Forest tomorrow aiming to end the hosts' 31-match unbeaten league run.
Steve Cotterill will do so with just three players on the bench, with Dave Kitson and Greg Halford suspended.
His defence have also shipped in three goals in each of their past four matches.
Last season, Cotterill formed a firm friendship with Davies while manager of city-rivals Notts County.
But Davies' heart does not go out to the Pompey boss over the continued plight of his club.
The Scot said: 'I don't have sympathy for him. We all have worries and concerns.
'We all have problems and issues. Every club is the same. I don't expect any club in the league to start worrying about us.
'I am sure they will not expect us to be concerned for them.
'It is a difficult time for them, but all you can do at any club is do the best you can with the resources you have got to work with. That is what we do and I am certain that is what Stevie is doing at his club.
'Being in football management, you learn not to look too far ahead.
'I know Steve well. I know his qualities and the work ethic he has got. He will have his team organised and his players prepared.
'But he will know to expect the same thing from us.'
Forest have the last unbeaten home record in the Championship.
In the process, they have conceded just 10 goals at the City Ground this season.
