Accorcing to oddschecker.com it seems Mark Bowen is the clear favourite for the Norwich job. Early days in the betting stakes I know, but this is certainly something I would not want to see happen at this stage of the Hughes/Bowen partnership.
As with many good number 2's they always like to see if they can manage the number 1 slot and with Bowen's history with norwich it wouldn't surprise me if there was something in it.
