Fabio Grosso opened the scoring in the 11th minute in the Group Eight match before his Juventus team-mate Vincenzo Iaquinta doubled the Azzurri's lead shortly before half-time.

The outcome sees the world champions go four points clear at the top of the group and leaves them needing just a point away to second-placed Republic of Ireland in October to go through.

Montenegro remain without a win in their qualifying campaign after letting a second-half lead slip away against Cyprus.

Captain Mirko Vucinic handed the home side a 57th-minute lead with a penalty, but Cyprus drew level seven minutes later when Ioannis Okkas netted.

Zoran Filipovic's team, like Cyprus, had seen their hopes of a surprise top-two finish disappear much earlier in the campaign so were playing for national pride.
