Nineteen of Daniil Medvedev's 21 championships have been won on hard surfaces
A comeback Medvedev claimed his initial trophy for 882 days with success over Frenchman Moutet in the Almaty Open title decider.
The Russian, a former world number one, has experienced a torrid period, managing just one match at the Grand Slams and undergoing a setback at the New York tournament.
The player's unpredictability on the professional circuit - and issues with his serving in especial - caused him falling of the world's top 10 and eventually parting ways with former coach his previous coach.
Presently working with Johansson and his other coach, he has gradually improved in the last few weeks - climaxing in a hard-fought three-set triumph over challenger Moutet.
It is Medvedev's maiden title following the 2023 Rome Masters and maiden on a hard court from March of that year.
Victory also signifies Medvedev has won 21 victories at twenty-one distinct events.
"For the first time I have attended a tournament with my children simultaneously, so to secure a title is especially meaningful," said tennis professional Daniil Medvedev.
"This title is in tribute of my child my daughter, because the initial championship I got when my first daughter Alisa was delivered was for her."
The tennis star, the past champion, had lost his previous six title deciders, featuring in Halle previously this season.
His counter-punching approach and recurring emotional displays on the tennis court had caused observers to doubt if his ability to perform at the top level was concluded.
But the athlete has altered his approach in the past month, attempting to advance forward and compete assertively, supported by an better serve.
The champion recovered from a break down in the first set against the difficult Frenchman, taking four of the concluding five points to go ahead.
Both players swapped service breaks in the second set before Moutet, attempting for his first tour victory, took control to push for a third set.
He rescued four early-game opportunities in a competitive final set before Medvedev secured a break to that score to close out the victory.
Appropriately, 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.
