Coach Van Sy Son said after the 0-1 loss to Da Nang in round 23 of V.League 2024-2025: "Quang Nam needs a new change. I informed them that I had sent a message to the board of directors to resign. Maybe a new coach will come, breathing new life into the team. I will take a break after this match. The most important thing is to wait for the leaders' opinions.
I often go back, who knows, there is a new vitality, it is better for the players who are stagnant like this. Not that I gave up, I wanted to take a step back so that some coach could come back to give the whole team a new wind. As for who can replace me, let the board decide."

Facing Da Nang at Tam Ky Stadium, Quang Nam had a better advantage from the first minute of the match. However, goalkeeper Van Cong's mistake at the end of the first half caused Quang Nam to concede a goal.
