Campbell: Portsmouth sales would be suicidal
The Blues skipper is convinced their European aspirations will be harmed if Harry Redknapp's squad breaks up.
Among them are Matt Taylor, who Redknapp has admitted will be allowed to leave if he wished to go.
He told The News: 'We are losing the guys for a month or six weeks to the African Nations but it's not that bad.
'We've got players who can fill in, great pros, so it won't hit us that much.
'The quality of players is a lot better in the squad, everyone is there.
'What we can't afford to do, though, is lose a couple of the fringe players.
'It would be suicidal to let players go, we need them all here.
'It's about having a strong squad, keeping a strong unit, everyone is important. 'It's definitely something to be wary of.'
