The 28-year-old also helped Italy win the 4x100m relay in Tokyo and he won the sprint title at the 2022 indoor world championships, but he has been dogged by injury problems since.

“I’m ready to race, to taste those unforgettable emotions again,” Jacobs said in an Instagram post ahead of this month’s athletics world championships in Budapest.

“Two years after my victory in the 100 metres at the Olympics, I’m reliving an unmatchable emotion, a triumph that rewrote my story.

“Today the echo of that success rings inside me.

“I ask myself to get back on track, to feel the energy of the finishing line again, the passion of competition”.

Back in June, the popular sprinter said he had been hurt by criticism of his recent under-par performances but would come back stronger, being “reborn”.

In a Diamond League meet in Paris then, Jacobs came seventh with a slow time of 10.21 seconds, in a sprint won by American Noah Lyles in 9.97 seconds.

When he won the first of his two gold medals in Tokyo, before the 4x100m relay gold, Jacobs set a European record of 9.80 seconds in the 100m final.

His disappointing season continued when he pulled out of the European Games in Poland on June 23-25.

This followed a number of other occasions in which he was forced to skip events through injury.

After that withdrawal, Jacobs put up a long post on his Instagram profile, explaining his feelings and also his bitterness, but emphasising his will to get back on the scene.

“In a moment all achievements seemed to be worth nothing anymore,” he wrote then.

“And I’m very sorry, because it would be nice if in such complicated moments I could be supported.”

Jacobs explained that he returned to the track “despite knowing that I was in no way ready” and then promised: “I have so many fears, but I am aware of all the ones I have faced and overcome.

“And I will be reborn again,” he posted.
