Normann is now over 21 so would have to be included in the 25 if he stays, or be exiled only to the U23s. Similarly Ahannach (though he is long term injured). I think Collar and Barclay are close to this boundary too, but possibly that will be next year's problem. On balance I think another loan...
Assuming we get in a winger and a CB, and Suttner stays.
That leaves Norwood, Skalak, Towell, Normann, Tau and one of Baldock/Hemed outside the 25.
Assumption would be we would be looking for permanent moves away for all but Normann and Tau who will probably go on loan.
