In July 2013, lifelong Feyenoord supporter Rooie Marck was battling terminal cancer and had been given only a short time to live.
His final wish was simple: to see his beloved club one last time.
Feyenoord invited him to De Kuip Stadium to watch the team's first training session of the season.
When he arrived, thousands of supporters delivered a surprise tribute. In the 12th minute, players stopped training and turned toward Marck as the entire stadium joined them.
Fans unveiled a giant banner featuring his likeness, lit green flares and smoke in his honor, and sang "You'll Never Walk Alone."
Overwhelmed by the gesture, Marck found the strength to stand up and walk toward the supporters despite his condition.
The crowd responded with a thunderous ovation as he thanked them for their support.
Just three days later, Rooie Marck passed away. His farewell at De Kuip remains one of football's most emotional and unforgettable tributes, a powerful reminder of the bond between a club and its supporters.
