Nineteen of the Russian's 21 championships have been won on hard surfaces
A revitalized the Russian player secured his maiden championship for over two years with success over opponent Moutet in the tournament title decider.
Medvedev, a ex- number one, has endured a difficult season, achieving just one win at the Grand Slams and undergoing a setback at the New York tournament.
Medvedev's unpredictability on the tennis tour - and issues with his serving in particular - resulted in him exiting of the world's top 10 and eventually parting ways with former trainer his previous coach.
Presently collaborating with Thomas Johansson and Goetzke, he has steadily improved in the recent weeks - culminating in a tightly fought three-set triumph over opponent Moutet.
This represents the player's maiden title since the Italian tournament and initial on a hardcourt since spring of that year.
Success also means the Russian has secured 21 championships at twenty-one various competitions.
"This marks the first occasion I'm at a event with my children together, so to win a title is really nice," commented ranked player Daniil Medvedev.
"This championship is in dedication of my child Victoria, because the maiden victory I won when my older daughter Alisa was born was for her."
Medvedev, the former major winner, had failed in his last six championship matches, featuring in Halle previously this season.
Medvedev's defensive approach and recurring emotional displays on the playing surface had caused observers to doubt if his ability to play at the top level was finished.
But the athlete has implemented adjustments in the past month, striving to advance forward and compete positively, reinforced by an improved serving game.
The champion recovered from a deficit in the opening set against the tricky Moutet, taking 4 of the final five points to take the lead.
The pair exchanged break points in the following set before the Frenchman, bidding for his maiden ATP Tour victory, gained dominance to create a third set.
Moutet saved four early opportunities in a competitive third set before the champion broke to fifteen to close out the victory.
Suitably, the winner earned the win with a rally at the net, with his opponent failing to control a shot after two hours and 38 minutes.
