'La Viola' have been in excellent form since the passing of club captain Davide Astori, winning six of their seven Serie A games, with the only blot on their copybook a 0-0 draw with SPAL.
Despite it being big-hitters Lazio in town on Wednesday night, Fiorentina continued their fine form, with Veretout at the double.
First, the former Aston Villa man curled a wonderful free-kick over the wall and beyond the diving Thomas Strakosha in the home goal to open the scoring with 16 minutes gone.
