Glave has made significant progress this season, breaking the 10-second barrier for the first time in legal conditions to win his first British title in June.
He has run sub-10 on six separate occasions, in all conditions, this season – including when he defeated the in-form Jacobs, a surprise Olympic champion five years ago, on his home turf in Italy.
That confidence was evident as Glave dominated his semi-final earlier in the evening, and he executed to perfection when it mattered most.
A talented junior, Glave was the fastest 17-year-old in the world in 2017 after he recorded a time of 10.21.
His progress has been disrupted by injury setbacks since, including a fracture in his back.
But, able to remain consistent with his training this year, Glave captured the gold medal he believed he was capable of winning two years ago.
The foundations of Glave’s recent progress has come from a focus on sharpening the first 40 metres of his race.
After hitting the front by the 30-metre mark, he never looked back – and continued running far beyond the finish line in celebration.
