Nineteen of Daniil Medvedev's twenty-one victories have been achieved on hardcourt
A comeback Medvedev secured his maiden trophy for 882 days with a win over opponent Moutet in the competition title decider.
The Russian, a former world number one, has endured a challenging season, achieving just one match at the big events and suffering a setback at the US Open.
Medvedev's unpredictability on the tennis tour - and difficulties with his service game in specific - led to him dropping out of the top ten and eventually parting ways with long-term mentor Gilles Cervara.
Currently training with Johansson and his other coach, Medvedev has gradually progressed in the last few weeks - climaxing in a hard-fought 7-5 4-6 6-3 win over opponent Moutet.
This represents Medvedev's first trophy since the 2023 Rome Masters and initial on a hard surface from March of the previous year.
Victory also indicates Medvedev has achieved 21 championships at twenty-one distinct competitions.
"It's the first time I am participating in a competition with my both daughters simultaneously, so to get a championship is particularly special," stated ranked player Medvedev.
"This victory is in honour of my child Victoria, because the maiden victory I won when my child her name was born was for her."
The tennis star, the past champion, had failed in his past six championship matches, comprising in Halle previously this season.
Medvedev's retrieving play style and frequent emotional displays on the tennis court had led some to doubt if his capacity to compete at the highest level was over.
However the player has altered his approach in recent weeks, making an effort to come to the net and play positively, backed up by an better serve.
Medvedev fought back from a disadvantage in the opening set against the difficult Frenchman, securing four of the final five points to go ahead.
The pair traded break points in the second set before Moutet, attempting for his initial ATP Tour championship, took control to push for a final set.
The opponent saved 4 early-game break points in a close third set before the champion won the break to that score to serve for the match.
Suitably, Medvedev earned the title with a rally at the front of the court, with the Frenchman incapable to handle a shot after over two and a half hours.
