It is now four defeats out of five for Girona in their inaugural Champions League campaign, after Michel Sanchez's side were beaten 1-0 at Sturm Graz.
The first half saw Girona have the better of the proceedings, although there were few chances created by either side. The best went to Ivan Martin, who somehow missed the target from inside the six-yard box.
That miss was punished in the second half as Sturm Graz opened the scoring on the hour courtesy of former Arsenal striker Mika Biereth.
Girona dominated the rest of the match, but they couldn't find the equalizer in Austria. Substitute Cristhian Stuani had two good chances late on, but was unable to convert either.
The result means that Gerona remains at three points in the standings of the league stage. They face Liverpool at Montilivi in their next match, and at this stage, their chances of progression are very low.
