IFK Göteborg is a Swedish professional football club based in Gothenburg. The club is often referred to simply as IFK, although this can be confusing as there are many other clubs in Sweden who use the abbreviation as part of their name. IFK Göteborg, formed on 4 October 1904, have won 18 national championship titles, five national cup titles, and two UEFA Cups. With Malmö FF and AIK, IFK Göteborg are often considered part of the "Big Three" in Swedish club football, who have 43 championship titles between them. IFK is arguably the most successful club in Sweden, and perhaps in Scandinavia, as it is the only Scandinavian team to have won a pan-European competition.
