So exactly who are FC Copenhagen?

FC Copenhagen host Shamrock Rovers in the third qualifying round of the Champions League, but who exactly are the Danish club?

FC Copenhagen have been the most successful club in Denmark in recent seasons, but they only came into existence as a club in 1992. Two clubs, Kjobenhavns Boldklub and Boldklubben 1903, merged in 1992 to found FC Copenhagen. Since then, FC Copenhagen has risen to become one of the big two 'New Firm' clubs in Copenhagen (the other being fierce rivals Brondby) as well as one of the most successful clubs in Denmark.

Since 1992, the club has won the Danish Superligaen nine times- including seven of the last ten. The Lions, as they are known, are also four time Danish Cup winners, one-time Danish League Cup winners and three-time Danish Super Cup winners. Copenhagen last year became the first Danish club to reach the second round. They drew with Barcelona, before beating Rubin Kazan and Panathinaikos. In the second round they lost to Chelsea on aggregate, despite drawing the home leg.

The Danish Superligaen is only two matches in to the current season, but Copenhagen have started reasonably well. They beat SonderjyskE 2-0 in their season opener and then drew 2-2 with OB last Saturday. OB were the closest thing Copenhagen had to competition in the Superligaen last season, coming second in the table on 55 points to Copenhagen's 81. Three players in particular played a big part in Copenhagen's success last season- the trio of forwards Cesar Santin and Dame N'Doye and midfielder Martin Vingaard scored 50 goals between them. N'Doye and Santin have scored one each so far this season.

Danish international Mathias Jorgenson stars at the back, with goalkeeper Johan Wiland winning six caps for Sweden. Their squad is littered with internationals- from Costa Rica's Bryan Oviedo to Swedish full-back Pierre Bengtsson. Danish underage internationals also litter the Copenhagen line-up- with Thomas Delaney a name which is sure to jump out to many Irish observers. Delaney is a highly rated Danish under-21 international midfielder, born in Denmark but of Irish-American descent.
