Trelleborgs FF, or simply Trelleborg, is a Swedish football club located in Trelleborg. The club, formed 6 December 1926, is currently (2007) playing in the highest Swedish league, Allsvenskan. Trelleborgs FF has participated 13 times in Allsvenskan and once in the UEFA-cup where the team eliminated Blackburn Rovers.
Trelleborg have had a reputation of being a less fashionable provincial side, making the most of limited resources and a small fan base. The club's glory days arrived in the early nineties when they won promotion to allsvenskan for the second time and finished third in 1992, the so far best placement, and fourth in 1993.
Tipped for demotion at the start of most seasons, the team scrambled through the late nineties with effective, but not very attractive, defensive long ball tactics. Trelleborg's stadium, Vångavallen, was even called "Tjongavallen" (from swedish "Tjonga" - kicking a football far away without direction). The team was demoted in 2001, finishing last after a disappointing season. During their third spell in Allsvenskan the demotion was somewhat ironic since it came after the Trelleborg board hired the dane Ole Mørk who were supposed to change the Trelleborg style of play into a more attractive short-passing game.
