Confirmed yesterday on the official site.
No great surprise although his performances since arriving from Inter didn't necessarily justify an extension.
Even with the extra workload we will face next season with European participation it is still difficult to see Vieira featuring in too prominent a role - particularly if we do land a James Milner for instance.
That said, he will be a useful presence for sure. Experienced, a winning mentality and someone who clearly has the ear of Roberto Mancini - which could also mean a progression into a coaching role down the line.
