Nineteen of the Russian's twenty-one championships have been won on hardcourt
A comeback Daniil Medvedev won his first trophy for nearly 30 months with victory over opponent Moutet in the tournament championship match.
Medvedev, a former world number one, has experienced a difficult season, winning just one win at the big events and suffering a meltdown at the US Open.
His varied form on the professional circuit - and difficulties with his service game in especial - resulted in him falling of the elite rankings and finally splitting with long-time trainer his previous coach.
Presently collaborating with Johansson and Rohan Goetzke, he has consistently advanced in the last few weeks - peaking in a hard-fought competitive victory over opponent Moutet.
This represents Medvedev's initial championship following the Rome competition and maiden on a hard surface from that period of the previous year.
Success also indicates he has won 21 titles at 21 different competitions.
"For the first time I'm at a tournament with my both daughters together, so to win a trophy is really nice," stated world number 14 the champion.
"This championship is in honour of my child my daughter, because the maiden victory I got when my older daughter Alisa was delivered was for her."
The tennis star, the former major winner, had failed in his previous six finals, comprising in Halle in the past months.
The player's counter-punching strategy and frequent reactions on court had caused observers to doubt if his capacity to perform at the elite level was concluded.
However the athlete has altered his approach in the past month, attempting to come to the net and play assertively, reinforced by an better serve.
The champion came back from a deficit in the initial set against the challenging opponent, taking four of the concluding five points to go ahead.
The pair traded break points in the following set before the Frenchman, attempting for his initial professional victory, took control to create a third set.
Moutet saved 4 early chances in a close deciding set before Medvedev broke to that score to close out the victory.
Suitably, the winner secured the title with a rally at the net area, with Moutet unable to handle a return after two hours and 38 minutes.
