Bruce needs to look closer to home as to who will go in the summer as his job is not entirely safe but, back to the question in hand and the players who I'd keep out of the 25 man squad
Gordon, Mignolet although I think Gordon will go nothing malicious in that but just an inkling.
Bardsley, Adams (not seen him so will give him the benefit), Turner not my favourite player but, will come good I think.
Catts, Henderson (if we can keep hold of him), Meyler, Knott (see Adams above), Sessignon bit of a cliché but needs more time.
Campbell, Gyan, Lynch and Noble (again see Adams above). Welbeck will be back at Man Utd to either be loaned out again or as a first team player there.
The rest are in my opinion surplus to requirements although I would definitely try to tempt Zenden with a coaching role.
14 out of 25 is fairly pitiful but like it or not SAFC is a business and hard decisions need to be made in the summer from top to bottom.
