[2] On 11 December 2009, it was announced in the Bulgarian media that CSKA Sofia had an interest in signing the midfielder.

After a short spell in Bulgaria at CSKA Sofia, Pancu returned to Romanian football later in 2010 to play for FC Vaslui, but had a difficult time breaking into the first eleven with strong competition from Wesley and Mike Temwanjera.

On the 28th gameweek of the 2004/05 Süper Lig season, during a derby match against Fenerbahçe, with the score at 2–3, Pancu replaced Óscar Córdoba, after the goalkeeper received a red card and Beşiktaş had already used all their substitutes.

After conceding a penalty, Pancu kept Fenerbahçe at bay until Koray scored the fourth goal for Beşiktaş in the fifth minute of added time.

[4][5][6] He later stated that he felt uncomfortable being labelled as a goalkeeper, as his native playing position was a forward.
