"If you want to be president of a League with 41 clubs instead of 42, you must go," Geronimi told RMC radio on Sunday.
"What happened last night is unacceptable. Sporting (Bastia) demands that he goes."
Bastia lost 4-0 to Paris St Germain, who claimed their fifth League Cup trophy with doubles by Zlatan Ibrahimovic and Edinson Cavani.
In 2012, Thiriez did not hand Bastia their Ligue 2 champions' trophy.
