He is the bassist, vocalist, and primary songwriter for the Swedish punk rock band Millencolin and also has a solo career with four studio albums.

The title comes from the name of an imaginary football team that he and his brother pretended to play in when they were young.

On 20 April 2003, the band cancelled their US Tour after Nikola reported the disappearance of his brother, Miodrag Šarčević.

On 2 December 2009, Šarčević announced on his official Facebook page that he would release his third solo record "Nikola & Fattiglapparna" in 2010.
