Diaby - Vital

Given the current dearth of centre-backs we have, Mertesacker and Koscielny have to be first and second for me. Losing any of the other three would be a big loss but we have at least some competent backup in their positions (Wilshere for Ramsey, Cazorla for Ozil, Walcott/Ox for Sanchez, etc). If, however, we lose Mert or Kos for a long period without bringing in another CB (especially if Vermaelen goes), we're screwed.

All are equally important.

Agree with D'J all are equally important. BUT Merts.and Kos. are more equally important than the others, as there is a distinct lack of alternatives as cover
