At international level, Wisła has competed in all three of the European competitions. The club's greatest success came in the 1978–79 season, when Wisła was able to reach the quarter-finals of the European Cup, eventually to be knocked out by Malmö FF 3–5 on aggregate. Most recently, Wisła narrowly missed out on a chance to compete in the 2005–06 UEFA Champions League group stage, being defeated 4–5 by Panathinaikos after extra time.[3]
