From that Bosman list id go for...
Raul Garcia
Marc bartra
Montoya
Stefano celozzi
Mame diouf
Alex esswein
Aaron hunt
Those few would add a lot of quality to our team.... Now I'm not saying sign all of them but if we Don't have any money to spend on transfers but can spend on wages, players like the above would be very astute acquisitions.
Personally speaking all those players are a good step up of what we have currently available ( not including injured players) diouf on a contract smaller than bents then shifting him out would make more sense to me... Also diouf has more to his game than bent has to his.... More physicality and a good scoring ability!
