Nineteen of Medvedev's twenty-one victories have been earned on hard surfaces
A resurgent the Russian player secured his initial championship for over two years with success over opponent Moutet in the tournament championship match.
The Russian, a former number one, has endured a torrid period, winning just one win at the major tournaments and suffering a meltdown at the US Open.
His varied form on the tennis tour - and difficulties with his serve in specific - resulted in him dropping out of the elite rankings and finally parting ways with long-time trainer his previous coach.
Currently working with Johansson and Rohan Goetzke, Medvedev has steadily progressed in the last few weeks - culminating in a closely contested three-set win over opponent Moutet.
This represents the player's maiden championship following the Rome competition and maiden on a hard surface from spring of that year.
The win also indicates Medvedev has secured twenty-one titles at 21 various events.
"This marks the first occasion I'm at a tournament with my children simultaneously, so to secure a title is especially meaningful," stated world number 14 Daniil Medvedev.
"This championship is in tribute of my second daughter Victoria, because the first title I won when my first daughter Alisa was born was for her."
Medvedev, the past champion, had failed in his last six finals, including in Halle previously this season.
The player's counter-punching play style and recurring reactions on the tennis court had prompted observers to question if his skill to perform at the highest level was over.
Yet the athlete has altered his approach in the last few weeks, making an effort to come to the net and compete aggressively, backed up by an improved service.
The champion recovered from a deficit in the first set against the tricky opponent, taking 4 of the concluding five exchanges to gain the advantage.
The competitors traded service breaks in the second set before the challenger, attempting for his maiden tour victory, seized the initiative to force a decider.
The opponent saved 4 early-game break points in a close third set before Medvedev secured a break to 15 to close out the victory.
Appropriately, he clinched the title with a rally at the front of the court, with Moutet unable to manage a volley after two hours and 38 minutes.
