19 of the Russian's twenty-one victories have been achieved on hard courts
A comeback Daniil Medvedev claimed his initial title for 882 days with success over opponent Moutet in the tournament final.
Medvedev, a ex- number one, has experienced a torrid year, winning just a single victory at the big events and undergoing a meltdown at the US Open.
Medvedev's varied form on the ATP Tour - and issues with his serve in specific - caused him dropping out of the world's top 10 and eventually splitting with former coach Cervara.
Now training with his coach and his other coach, Medvedev has steadily improved in the recent weeks - culminating in a closely contested three-set triumph over Frenchman Moutet.
It is his initial title following the Rome competition and maiden on a hard surface after March of the previous year.
Victory also indicates Medvedev has achieved 21 championships at twenty-one distinct events.
"It's the first time I'm at a event with my two daughters together, so to secure a title is especially meaningful," commented world number 14 the champion.
"This title is in tribute of my younger daughter her name, because the initial championship I got when my child my daughter was born was for her."
The athlete, the former major winner, had lost his last six championship matches, featuring in the German tournament in the past months.
The player's retrieving strategy and regular outbursts on court had led some to wonder if his ability to compete at the elite level was finished.
But the athlete has altered his approach in the last few weeks, making an effort to come to the net and perform assertively, backed up by an improved serve.
Medvedev recovered from a disadvantage in the initial set against the tricky Moutet, winning four of the final five exchanges to go ahead.
The pair swapped service breaks in the second set before the challenger, bidding for his maiden ATP Tour title, gained dominance to push for a decider.
The opponent defended four early-game opportunities in a competitive final set before the Russian secured a break to that score to close out the victory.
Suitably, the winner earned the title with a point at the front of the court, with the Frenchman unable to handle a volley after a lengthy match.
