Genoa were narrowly beaten 1-0 by French side Bastia, but Tomas Rincon and Iago Falque got their debuts.
The Grifone set down in Corsica just seven days before Bastia’s first competitive match of the season.
Juraj Kucka thought he had to score from point-blank range early on, but was denied by a brave Francois Modesto block.
Christopher Maboulou and Floyd Ayite had dangerous efforts, but Bastia eventually scored when a corner was not cleared effectively, allowing Guillame Gillet to turn in from close range.
Summer signing Diego Perotti’s volley skimmed the woodwork, as did an Aleandro Rosi header, then Yannick Cahuzac and Ayite tested Albano Bizzarri.
Genoa gave Iago Falque and Tomas Rincon their debuts in the second half.
