Italy had over 60% possession in the first half but former Manchester City striker Edin Dzeko gave the visitors the lead with a close range finish.

Lorenzo Insigne equalised after half-time with a superb right-footed volley.

The Azzurri continued to push forward and Verratti curled in the winner from inside the area with four minutes left.

Italy remain top of Group J and play their next qualifier away to Armenia on 5 September, while Bosnia host Liechtenstein on the same day.
