Nineteen of the Russian's 21 titles have been won on hardcourt
A revitalized Daniil Medvedev secured his first championship for 882 days with victory over opponent Moutet in the tournament title decider.
The athlete, a ex- top-ranked player, has endured a torrid year, winning just one win at the big events and suffering a setback at the US Open.
His inconsistency on the tennis tour - and issues with his serving in particular - caused him exiting of the world's top 10 and ultimately separating with long-term trainer Cervara.
Presently training with Thomas Johansson and Rohan Goetzke, the tennis star has gradually advanced in the recent weeks - climaxing in a hard-fought three-set victory over challenger Corentin Moutet.
It is the player's first championship following the Rome competition and initial on a hard surface from spring of that year.
Success also means Medvedev has won 21 victories at twenty-one different competitions.
"It's the first time I'm at a event with my children together, so to win a championship is especially meaningful," said tennis professional Medvedev.
"This victory is in dedication of my child my daughter, because the first title I got when my older daughter her name was born was for her."
The athlete, the 2021 US Open champion, had failed in his previous six finals, comprising in the German tournament previously this season.
The player's retrieving play style and recurring outbursts on the tennis court had led commentators to doubt if his ability to perform at the top level was over.
But the 29-year-old has altered his approach in recent weeks, striving to come to the net and compete aggressively, supported by an better service.
He recovered from a break down in the initial set against the difficult opponent, securing 4 of the last five exchanges to gain the advantage.
The pair swapped service breaks in the middle set before the Frenchman, striving for his maiden tour victory, seized the initiative to create a third set.
The opponent saved 4 initial chances in a tight deciding set before the champion broke to that score to secure the win.
Appropriately, he earned the win with a rally at the front of the court, with his opponent incapable to handle a volley after a lengthy match.
