19 of Daniil Medvedev's 21 championships have been won on hardcourt
A resurgent the Russian player claimed his first title for over two years with victory over Frenchman Moutet in the tournament title decider.
Medvedev, a former top-ranked player, has had a challenging season, achieving just one win at the major tournaments and suffering a setback at the New York tournament.
His varied form on the tennis tour - and issues with his serving in especial - caused him falling of the top ten and ultimately splitting with long-term coach Gilles Cervara.
Currently training with Johansson and Goetzke, the tennis star has gradually advanced in the last few weeks - culminating in a closely contested competitive victory over challenger Moutet.
This represents his first title since the Rome competition and first on a hard court after that period of 2023.
Success also means he has achieved twenty-one titles at 21 distinct tournaments.
"It's the first time I'm at a tournament with my two daughters together, so to win a title is particularly special," commented ranked player the champion.
"This championship is in honour of my second daughter Victoria, because the maiden victory I won when my first daughter my daughter was born was for her."
The athlete, the former major winner, had lost his past six title deciders, comprising in Halle in the past months.
Medvedev's counter-punching strategy and frequent emotional displays on court had prompted observers to question if his ability to play at the elite level was over.
However the player has made changes in the last few weeks, making an effort to approach the net and play positively, backed up by an better serve.
The champion fought back from a break down in the first set against the difficult Frenchman, taking 4 of the concluding five games to take the lead.
The pair traded service breaks in the middle set before Moutet, bidding for his maiden professional title, seized the initiative to push for a final set.
The opponent saved four initial chances in a tight final set before the champion broke to that score to serve for the match.
Appropriately, Medvedev earned victory with a rally at the net area, with his opponent incapable to handle a shot after a lengthy match.
