As a veteran of Ajax-Feyenoord fixtures, Heitinga has seen first-hand the consequences of deep-rooted hostility between rival sets of fans.
And it’s why this afternoon’s short trip across Stanley Park will make a refreshing change for the battle-hardened 26-year-old.
“This is a derby whereas Ajax-Feyenoord is more like history and hatred, the fans really hate each other,” says Heitinga. “It’s unbelievable.
“For example, if you go from Ajax to the Feyenoord stadium there will be a police helicopter above the team coach and police cars outside.
“It felt like you were in a movie. When you reached the city the main roads would be blocked off with police too, and this was all for a football game. It is not normal.
“Here this is more respect and nothing should happen inside the stadium.
“In Holland there will be a big fight between the fans. Last weekend it was Feyenoord-Ajax and the Ajax supporters were not allowed inside the Feyenoord stadium.
“I played 18 years for Ajax and never lost a game against Feyenoord once I turned professional and, like the derby here, it is not a game about the league competition. It means different things to that.
“I started at Ajax when I was seven and played many times against Feyenoord, and we even had problems at that age level with fanatical supporters who would come to these games. Even kids’ games. Unbelievable.
“I enjoyed these games though, I have to be honest.”
