Serie A champions maintained their unbeaten start to the season with a win at Parma.

With just two minutes on the clock, Mario Mandzukic gave Juventus the lead but Parma equalized before half-time when Gervinho scored with a close-range finish.

New signing Cristiano Ronaldo is yet to score since joining the Old Lady, but his side grabbed the victory through French midfielder Blaise Matuidi' second-half goal.
