McFarland calls for improvement despite Ulster's eight-try win

Dan McFarland says he wants his Ulster side to keep on learning despite an eight-try victory over Zebre in the Pro14 on Saturday night.

McFarland added that he was impressed with how his side performed in the 54-7 win over the Italian outfit.

Hat-trick hero Rob Herring says an improvement at the set-piece was the basis for the win.
