A mind-blowing 15 first-team players could eventually walk away, leaving new head coach and sporting director with a huge amount of work to do over the summer.
Five of those are the loanees currently calling the south coast home. But 10 are senior players currently on permanent deals, individuals who could walk away for nothing if they so wished.
The Blues are yet to enter fresh talks with anyone whose deal is now into it’s final five months, with Mousinho understandably wanting time before making a call.
Finances, a player’s desire to stay and offers from elsewhere are just some of the factors that must be considered before any decision is made.
But who is likely to stay from that 10 and who could eventually end up leaving?
We have a look at what could unfold in May.

The midfielder has fought back well from the leg break he suffered back in August. Is a reliable performer when called upon, while his experience may come in handy if an influx of youngsters arrive in the summer. You suspect there'll be no guarantee of regular starts if he stays, but worth keeping him around for another season at least. Photo: Jason Brown

The midfielder was one of very few positives to emerge as Pompey's season started to unravel in the autumn. He's everything Pompey want from their players - aggressive, energetic, pacey, versatile and forward thinking. The Blues would be foolish not to offer the former Charlton and West Brom youngster a new deal. However, with the likes of West Brom interested, whether stays could be out of their hands.

On a personal level, the winger deserves a bit of luck after suffering two ACL injuries in two years. But with football being an business, there's little room for sentiment. That being said, perhaps the Blues can offer the 21-year-old a pay-as-you-play deal and see how that transpires. Picture: Rogan/Fever Pitch Photo: Rogan
