Sassuolo grabbed an unlikely point at the San Paolo this evening to heap more pressure on Napoli coach Maurizio Sarri. In a first-half dominated by the home side, a fabulous curling effort by Lorenzo Insigne looked as though it would lay the foundations for a comfortable night's work. But a second-half fight back from Di Francesco's team, was rewarded in the closing minutes when substitute Gregoire Defrel (a player already linked with a move to the partenopei) scored a precious equaliser.
