Nineteen of the Russian's 21 titles have been achieved on hard courts
A revitalized the Russian player won his maiden championship for 882 days with victory over Frenchman Moutet in the tournament title decider.
The athlete, a former number one, has endured a challenging period, winning just one win at the major tournaments and undergoing a setback at the New York tournament.
The player's unpredictability on the professional circuit - and struggles with his serve in particular - resulted in him exiting of the elite rankings and eventually separating with former trainer Cervara.
Now training with Johansson and Rohan Goetzke, the tennis star has gradually advanced in the last few weeks - peaking in a hard-fought competitive triumph over challenger Corentin Moutet.
This represents Medvedev's maiden championship following the Italian tournament and initial on a hard surface after that period of 2023.
Success also means the Russian has achieved twenty-one victories at 21 different tournaments.
"For the first time I am participating in a event with my two daughters together, so to get a trophy is particularly special," commented world number 14 Daniil Medvedev.
"This championship is in tribute of my younger daughter Victoria, because the maiden victory I got when my first daughter Alisa was delivered was for her."
The tennis star, the 2021 US Open champion, had lost his previous six finals, featuring in Halle in the past months.
Medvedev's defensive strategy and recurring emotional displays on the playing surface had caused some to wonder if his capacity to compete at the elite level was concluded.
Yet the player has made changes in recent weeks, striving to advance forward and play assertively, backed up by an improved service.
The champion recovered from a break down in the first set against the tricky opponent, taking four of the last five exchanges to gain the advantage.
The competitors swapped break points in the following set before the Frenchman, bidding for his first professional victory, gained dominance to push for a final set.
Moutet saved 4 initial break points in a competitive final set before Medvedev secured a break to fifteen to serve for the match.
Suitably, Medvedev clinched victory with a rally at the front of the court, with the Frenchman failing to manage a shot after two hours and 38 minutes.
