Nineteen of Medvedev's twenty-one championships have been won on hard surfaces
A revitalized the Russian player claimed his initial trophy for nearly 30 months with a win over Frenchman Moutet in the tournament title decider.
Medvedev, a former top-ranked player, has experienced a torrid season, winning just one match at the major tournaments and undergoing a meltdown at the New York tournament.
His varied form on the ATP Tour - and issues with his service game in especial - led to him dropping out of the top ten and finally splitting with former trainer Gilles Cervara.
Presently training with Johansson and his other coach, he has gradually progressed in the last few weeks - culminating in a closely contested three-set triumph over challenger Corentin Moutet.
It is his maiden championship after the Italian tournament and first on a hard court since spring of 2023.
Success also signifies the Russian has secured twenty-one victories at 21 various tournaments.
"For the first time I have attended a tournament with my both daughters together, so to secure a trophy is particularly special," commented world number 14 Medvedev.
"This victory is in dedication of my child her name, because the maiden victory I won when my older daughter Alisa was born was for her."
The athlete, the 2021 US Open champion, had been defeated in his past six finals, including in Halle previously this season.
His counter-punching play style and regular outbursts on the playing surface had caused observers to doubt if his skill to play at the top level was over.
Yet the athlete has altered his approach in the past month, striving to come to the net and compete positively, supported by an enhanced serve.
Medvedev came back from a disadvantage in the first set against the challenging Frenchman, winning four of the final five exchanges to gain the advantage.
The competitors exchanged break points in the second set before Moutet, striving for his initial tour title, took control to force a third set.
He defended 4 early opportunities in a competitive third set before the champion secured a break to that score to secure the win.
Suitably, the winner secured the title with a shot at the net area, with his opponent incapable to control a volley after a lengthy match.
