Chris Samba (when we finally get him). I'm struggling to think of anyone in the existing squad that is truly pivotal which says a lot about our season. Of course a certain Mr Park is the actual first name of the teamsheet. Rumour has it the marketing people have actually had them pre-printed.
Granero, Hoilett, Taraabt should be guaranteed a place imo but Granero is definitely the first for me.
