I think with him in the squad we should have our defense sorted since he can play RB as well as CB -- I would think he will be an excellent cover for the SHs.
Hyypia, Henchoz, Babbel, Carragher / Xavier at CB
Babbel, Carragher, Xavier, Wright at RB
Carragher, Riise, Xavier, Vignal at LB
I think that should give us enough cover for every location at the back. If Rigott signs it will be even better but as its stands I think we will do alright.
