Ajax from Amsterdam are Feyenoord's archrivals. The two clubs share a long history together and matches between the two clubs are called the "Klassieker" ("The Classic"). The rivalry is not only between the two teams, but also a confrontation between the two largest cities of the country, Amsterdam and Rotterdam, two cities with extreme differences in attitude and culture. The meeting between the two teams is still considered to be the biggest match of the season. In the past, there have been many clashes between the supporters of both clubs, of which the Beverwijk clash in 1997 is the most infamous, with Ajax fan Carlo Picornie being killed and several others injured. In 2004, Feyenoord player Jorge Acuña was taken to hospital with head, neck and rib injuries after Feyenoord players were attacked by Ajax hooligans during a match between the reserve teams of both clubs. Another Feyenoord player, Robin van Persie, had to be rescued by Ajax coach John van 't Schip and player Daniël de Ridder. In 2005, riots before and after the match occurred in Rotterdam and were considered to belong to the worst in the history of Dutch football. Rotterdam is the city with the most professional teams in the Netherlands. Besides Feyenoord there are Sparta Rotterdam and Excelsior. There is a rivalry between the teams, mostly between Feyenoord and Sparta as Excelsior used to be Feyenoord's feeder club, but it is not comparable to other local derbies. The rivalry between Sparta and Feyenoord is mostly seen on the Sparta side. Some Sparta fans have refused to enter Feyenoord's De Kuip stadium, even when Sparta had reached the KNVB Cup final, which was played in De Kuip. In the 1950s there was much more of a rivalry. One of the key factors for these feelings was footballer Tinus Bosselaar, who moved from Sparta to Feyenoord in 1954 before Sparta re-signed him, despite Feyenoord trying to prevent the deal in court. Feyenoord also have a rivalry abroad against Tottenham Hotspur following several violent clashes between the club's supporters and Tottenham's "link" to Ajax.
