O'Neill hits back at 'charlatan' Di Canio

Martin O'Neill has hit back at Paolo Di Canio with the spat between the two former Sunderland managers showing little sign of abating.

The Ulsterman, who was replaced by the Italian following his own sacking by the Black Cats in March, described his successor as a "managerial charlatan" following a sustained attack on his regime during his stint at the Stadium of Light.
