The Blues currently have 13 out-of-contract players when the campaign comes to a close, with John Mousinho set for crunch talks next week.
While a number of the head coach’s squad could depart, sporting director Rich Hughes has detailed at least nine or 10 new arrivals through the doors in the window.
But with only 13 men currently under contract beyond this term, where do the Blues need to recruit the most this summer?
We’ve broken down every position in the side to discover the true extent of work which could be needed in the market.
5. Left-back
Mousinho has insisted he is happy with his options at left-back, with Connor Ogilvie expected to have the option in his contract taken up by the club. There is still much speculation over the future of Denver Hume, who has started just once under the new head coach. Should the ex-Sunderland man depart, it will be likely the Blues enter the market for a new left-back. Liam Vincent is also an option after his impressive loan stay at Worthing. Photo: Jason Brown
6. Centre midfield
The Blues are well stocked in the centre of the park with Marlon Pack, Joe Morrell and Tom Lowery all contracted beyond this summer. It is likely Louis Thompson, Ryan Tunnicliffe and Jay Mingi could depart when their contracts expire. Should that be the case, Mousinho could be looking at as many as three new faces in midfield should he continue playing with a three. A decision on Harry Jewitt-White will also have to be made should the head coach view him as a regular in the first team. Photo: Jason Brown
7. Right-wing
With Owen Dale returning to Blackpool at the end of his loan, Paddy Lane and Reeco Hackett remain the two options on the right. Following his return from injury, Lane has impressed while the latter has failed to make the last two squads. That has raised questions over his future as he heads into the final 12 months of his deal. Mousinho has insisted he must strengthen his attacking threat on the wing in the summer. Photo: Jason Brown
8. Attacking midfield
Mousinho recently stated the number 10 role is one of the areas which will take priority in the window. The Blues have struggled to cement a regular attacking midfielder, with Michael Jacobs, Joe Pigott and Hackett all sharing the responsibility throughout the campaign. The need for more pace, creativity and firepower in attack is a must with Colby Bishop in need of more service up front.
