19 of Medvedev's twenty-one victories have been achieved on hard courts
A revitalized the Russian player won his initial trophy for 882 days with a win over Frenchman Moutet in the tournament championship match.
The Russian, a former world number one, has endured a torrid period, achieving just one match at the major tournaments and undergoing a meltdown at the US Open.
The player's varied form on the tennis tour - and issues with his service game in particular - caused him dropping out of the top ten and finally splitting with long-time coach his previous coach.
Now collaborating with Johansson and Rohan Goetzke, Medvedev has steadily progressed in the recent weeks - culminating in a hard-fought 7-5 4-6 6-3 win over Frenchman Moutet.
This marks the player's maiden championship since the Rome competition and initial on a hardcourt after March of 2023.
Victory also signifies Medvedev has achieved 21 championships at 21 various events.
"This marks the first occasion I'm at a event with my both daughters at once, so to secure a championship is particularly special," said tennis professional Medvedev.
"This championship is in honour of my second daughter her name, because the initial championship I achieved when my child my daughter was born was for her."
Medvedev, the past champion, had lost his past six finals, featuring in that event in the past months.
The player's counter-punching approach and recurring emotional displays on the tennis court had prompted observers to doubt if his skill to play at the elite level was over.
However the player has altered his approach in the past month, attempting to come to the net and perform aggressively, reinforced by an improved service.
The champion recovered from a deficit in the first set against the challenging Frenchman, winning four of the last five games to gain the advantage.
Both players exchanged service breaks in the second set before the Frenchman, striving for his first professional victory, gained dominance to force a decider.
Moutet defended four initial opportunities in a tight final set before the champion won the break to 15 to secure the win.
Fittingly, Medvedev secured the title with a shot at the net area, with his opponent unable to manage a return after a lengthy match.
