I say sign up Burdisso on loan with a view for permanent deal around 3m euro. I think that would be pretty fair deal.
It is obvious Inter doesnt want him, and Burdisso went to hard time on a personal level, hence, I feel 2 years in Italia are not his trueself.
ATM, only dependable defender we have is Kovac. Tudor is injury prone and Legro is just crap. If we sign Givet, we would still a rotational player. Since Burdisso can play as a make shift right back, he would be just fine.
Balza, Chielli, Biri, Burdisso, Givet, Kovac, Tudor/Legro, Masiello sounds quite decent for Serie B.
