In a five-man midfield it would mean that one of Barton, Nolan and Jonas would've to sit down. A bit of rotation never hurts. Zoggy in the middle, Barton in the middle, Nolan in the middle, doesn't really matter, all that matter is that N'Zogbia and a new class strike would make us a top half team for many years. We'd still need a new CB and possibly new RB to even consider challenging for Europe in the league though.
Midfield with; Guthrie, Barton, Nolan, Tiote, HBA, Jonas, Zoggy + new backup DM (Reo-Coker?!?) Wouldn't be to shabby.
But we all know this isn't going to happen. So whatever...
