We need a player who can actually play defensive mid mate. When Gana goes to pasture we aren't looking or shouldn't be looking for a number 8 which he is who is great defensively to replace.
We should be looking to actually have an 8 more like KDH and a defensive midfielder behind both.
Gana is not an 8 in my eyes. I don't think there's too many who would classify him as such.
As I've said, he's definitely not a traditional deep lying 6, flanked by two 8s as you'd want in a 4-3-3
But we don't play 4-3-3, we play 4-2-3-1, so Gana was and still is the more defensive minded player of a double pivot.
We could go round in circles on this so, out of interest (and interest in moving the debate on) who would you like to see us sign as a CDM? A Luiz? Arguably he's not a proper no.6, more of a hybrid in the Gana mould as well
