Steve Cotterill has revealed his frustration as he bids to put his summer recruitment plans into overdrive.
Pompey will be left with just nine contracted players at the end of the season.
That meagre figure includes Tal Ben Haim – a player the club are desperate to off-load as they strive to reduce their wage bill.
Others staying include Liam Lawrence, Dave Kitson, Hayden Mullins, Jamie Ashdown and Ricardo Rocha.
That has left Cotterill requiring to bring in at least 10 players once the current campaign has ended.
It is a tall ask, with the club still hampered by their continued financial restrictions.
Cotterill admits such constraints imposed by Pompey’s owners are impacting dramatically upon his plans to recruit more players.
And he is concerned over the lack of progress being made as a result.
He said: ‘I can’t make any summer plans at the moment, I just can’t.
‘I would like to do a bit more but at the moment I can’t. Don’t ask why, that is just how it is.
‘There definitely needs to be some investment in the playing side, for sure.
‘We are still talking to a few people, so you never know.
‘They are still promising but I would like to be a bit more active with things, really.
‘I don’t want a massive squad, I just want one that is bigger than this year.
‘We want quality over quantity. There is no point having players for every day of the week when all they do is play on Saturday.
‘I think the possibility of a big turnover this summer will be dependent on what is available for me to use.
‘Finances will obviously dictate that.’
