However, the club holds the distinction of playing the first ever international club match hosted by a Croatian club since Croatian independence, a friendly against Sturm Graz played in February 1992, and they were also the first Croatian side to play abroad, when they played a friendly against Brighton & Hove Albion in England in the summer of 1991. In the following years the club's performances rapidly declined and in 1997 they were relegated to 2. HNL, and in 1999 further down to 3. The year 2000 proved to be a turning point, and in 2001 they bounced back to second level and in 2003 got promoted back to top level after six years of absence. In 2003 their main sponsor the ceramics factory Inker ceased sponsoring the club, so the club was renamed once again, to Inter Zaprešić. In the 2004–05 season they finished runners-up in the league, which is still their record-high finish. The following season Inter finally debuted in European competitions, but were knocked out in their first tie by Serbian side Red Star 7–1 on aggregate in the second qualifying round of the 2005–06 UEFA Cup, with Srđan Pecelj scoring Inter's only European goal to date. Inter's success between 2002 and 2005 was largely helped by players who were loaned from Croatian powerhouse Dinamo Zagreb (such as Luka Modrić, Vedran Ćorluka and Eduardo), so Inter's fortunes changed again once again after they were recalled to Dinamo. They slipped down to second level again in 2006, but managed to win promotion immediately in the 2006–07 season. The following years were a struggle and the main goal was to preserve Prva HNL status except in 2010–11 when the club surprisingly finished 5th overall. In 2013, they slipped down, for the third time in their history, to Druga HNL. As of 2015–16 season they play in Prva HNL again. Because of Zaprešić's geographic proximity to Zagreb, the hometown of GNK Dinamo Zagreb , Inter Zaprešić always struggled to attract people to games. Nevertheless, throughout the years, a group of fans managed to organise themselves into the supporters group called Divlje Svinje (Wild Pigs). In 1990's, some members of Bad Blue Boys who wanted a new challenge came together and cheered using the flares during the game of Inter Zaprešić. Few days later, the picture of them was released in daily newspapers and the event is known as the day when Wild Pigs were formed.
