Bastia believe they have a slim chance of defeating Paris Saint-Germain at home on Saturday and coach Frederic Hantz (pictured) said his shared background with PSG front-man Zlatan Ibrahimovic would be a help.
"We have a 10 percent chance of carrying it off. All week I have been focusing on this 10 percent," Hantz told a news conference on Friday.
"I have only one point in common with Ibra - I grew up on the fourth floor of an HLM (social housing project). It's an important point in common because we don't puff out our chests in front of the weak and we don't bow our heads in front of the strong," Hantz said. "We have to believe that we can win."
Bastia, who have lost their last three league games, are 12th on six points from five games, while unbeaten PSG are fourth on nine.
