i think that between de ceglie, criscito and molinaro that the LB spot is covered well for the next season...and can be remedied if needed next year. However the right back spot must be upgraded..with at least one of grygera or zebina sold (hopefully zebina....i think he is a solid player however too injury prone and high wages and older).
This would leave our defence as
RB. New signing , grygera , mellberg
CB. Chiellini, Cannavaro, Legrottaglie ,Ariaudo
LB. De Ceglie, Molinaro , Criscito
Keeping in mind that mellberg and criscito can cover for CB, and de ceglie can cover for LM. I think this is the most realistic defence we can hope for in 09/10 and it will hopefully allow de ceglie, chiellini, ariaudo, new rb and molinaro to improve under cannavaro.
