Dejan Stefanovic has tipped Pompey to send his Fulham side tumbling into the Championship.
The former Fratton favourite thinks the Blues will triumph against Roy Hodgson’s side on Sunday.
Stefanovic feels the team he joined last August lack the same quality Harry Redknapp’s men possess.
And he thinks that will stop the Londoners getting the three points they need to be assured of safety.
Stefanovic said: ‘It’s a massive game for Fulham and we need to win.
‘I think it is going to be difficult to pick up all three points. I think we will be lucky to get a point.
‘Pompey have lost their last three games and it was a draw before that.
‘They will want to have a win going into the FA Cup final.
‘I know Harry Redknapp and what his teams are like.
‘Pompey always want to win at home whatever the game is.
‘I think it will be tough to take a result.
‘The players are not bad here.
‘It is a squad which can just about survive, if they are lucky.
‘But if you ask me “Who is going to win?” I think it will be Portsmouth.’
Stefanovic will miss an emotional return to his former club after falling out of favour under Hodgson.
The 33-year-old stated he will be leaving the club in the summer.
Stefanovic said: ‘I’ve not played since the start of the year and it will be disappointing not to play in front of the Pompey fans again.
‘I’ve said I will be leaving in the summer whatever happens on Sunday.
‘The manager has bought his players and has his opinion. That’s football. It’s no big deal.’
