I'd let them all leave.
I'd rather Edmundson in the squad than Burgess and it sounds like Gerrard is due to sign once the embargo is lifted.
I would keep Dunne but on the basis on that Reckord is contracted until end of the season and we need a new left back unfortunately he has to go to create space for one as I can't see anyone wanting Reckord.
Croft - 10/20 minute impact player at best. Seems unable to affect a game positively from the start. His weight is likely to balloon soon as he gets a contract longer than 6 months.
Jahraldo-Martin - Barely seen him play, seems to have some pace but if he can't get in the squad ahead of everyone else then no point him being here.
Klok - Plenty of energy but appeared to be a yard or two off the pace constantly. Seems to have been injured for most of his time here.
Ladapo - Can't control a ball. Can't jump/head a ball. Most of the time looks like he can't be arsed.
CB, LB, CM, LW and ST all needed as a minimum (New manager also needed!). If we could get players in all those positions I'd then look to try and get another winger in aswell if possible.
CB appears to be Gerrard. LW I'd try to sign Martis on loan. Holloway would be a decent choice for ST if available. No idea on who could come in at LB and CM in middle of the season.
