The matches between Brondby and FC Kopenhagen might be decisive in the race for the championship as they are the most succesful clubs in Denmark. Brondby is from the working-class suburbs south of the city and was the first club to turn professional in 1985. FCK was founded in 1992 (fusion of KB and B 1903) and quickly gathered a big crowd as their stadium is located in the center of Copenhagen. Traditionally Brondby was known as a very social club while FC Kopenhagen was more of a business men's football club.
