The youngest previous tour winner was New Zealand's Danny Lee who was 18 when he triumphed at the Johnnie Walker Classic in Perth, Australia in February 2009.

Manassero started the day two shots behind leader Gary Boyd but a red-hot homeward nine and a collapse by the Briton led to victory for the teenager.

The Italian closed with a four-under 67 for a 16-under total of 268 to win comfortably from Spain's Ignacio Garrido (68) whose late spurt earned second place.

Manassero told Sky Sports: "It's just a fantastic feeling. I have always worked for this moment." Boyd, who shot a course-record equaling 63 on Saturday, slumped to a 74 to share third place at 11-under.

The Briton's challenge evaporated at the par-three 16th where he found water and carded a double-bogey five.
