Under coach Patrick Rahmen, FC Sion has developed a clear tactical identity that sets the team apart from others in the league. Sion's playing style emphasizes a blend of technical football and physical play. The focus is on moving the ball quickly and utilizing spaces effectively to breach the opposing defense. This philosophy has proven successful and helps keep the team competitive in the league.

A central element in Rahmen's tactics is the use of wing players. The width of the pitch is exploited to open up space in the center and increase pressure on the opponent's defense. Players like Winsley Boteli Mokango and T. Berdayes effectively take on this role by making penetrating runs, forcing the opponent’s defense to stretch and create gaps. This system also leverages the abilities of midfielders who can draw in from the wings to seek scoring opportunities.

Defensively, Sion has established a robust pressing game under Rahmen that forces opponents to make quick decisions. Players are trained to react immediately and regain possession in midfield. This approach is crucial as it can prevent opposing teams from gaining momentum in their build-up play. By increasing pressure on their rivals, Sion can gain more ball possession and control the game at will.

Another aspect is the flexibility of Rahmen's tactics. Depending on the opponent, FC Sion can make adjustments to neutralize the respective strength of the opposing team. This is evident in the varying formations and styles of play Sion demonstrates during different matches. Under Patrick Rahmen, it is clear that FC Sion not only impresses with its gameplay but is also strategically well-prepared to succeed in the league.
