who man....we have enough defender who else we need....zebina, grygera, criscto, chielleni, legro, boum, andrade(injured), molinaro....who else we need.....we have to wait until the summer...than we must sell boum, zebina, and buy 1 superclass defender not now....
EDIT: I forgot Brindelli..
While we have enough in numbers... the quality is questionable, and as a result, there is a need to field 2 defensive midfielders, stifling the offense and holding back players like Tiago.
Solid Defenders: Chiellini, Legrottaglie
Inconsistent Defenders: Molinaro, Criscito, Zebina, Grygera
Inadequate Defenders: Birindelli, Boumsong
Longterm Injury: Andrade
When you look at it this way... another defender is a must. Personally, I think a wingback is top priority. When healthy, there's plenty of depth at CB...
CB: Chiellini, Legrottaglie, Andrade, Criscito, Boumsong... and that's without pulling someone out of position.
LB and RB are a little different...
LB: Molinaro... after that its a hodge-podge of other players getting slotted in like Criscito, Salihamidzic or pulling Chiellini back to LB at the detriment of CB.
RB: Grygera, Zebina, Birindelli. Grygera is injury prone, Zebina is hot and cold, and as much as we like Birindelli... he's ready to retire. Salihamidzic can also slot in.
Therefore, the priority is a wingback. Firstly, a guy like Pasqual or Grosso to play LB, failing that, a RWB to replace one of the question marks.
