Lig, but even there he was mainly used a late substitute, resulting in him managing to score only one league goal. In early 2007, there were rumours that he would move to the Swedish Allsvenskan side Helsingborgs IF. He was however called back to Trabzonspor main squad for 2007/08 season by Trabzonspor Trainer Ziya Dogan after the loss of explosive striker Ersen Martin to injury, but did not feature. Teplice In January 2008 Jun was again on his way back to the Czech First League, this time joining FK Teplice on loan. After six months in the league, where he netted 4 goals in 14 league appearances, Teplice made his loan move permanent. He continued in similar form in the next six months, scoring 3 times in 14 appearances. In January 2009 he left FK Teplice on a six-month loan move to Austrian Bundesliga side SCR Altach.

He went on to score four times until the end of the 2009–10 season, making him second-best goal-scorer after Milenko Ačimovič with a total of nine goals and ten assists. As a result of this good first season, Austria Wien made
