The experienced defender is running out of patience as question marks remain over his future at Camp Nou
The 33-year-old's current contract with Barca is due to expire at the end of this season, but the Catalans have yet to inform Abidal whether or not he will be offered a new deal.
"Abidal is starting to get disillusioned with how long it takes for Barcelona to make a decision about his future," Venditelli told RAC1.
"It is not so much whether Barca want to continue with him or not, but the uncertainty is getting increasingly difficult for Eric.
"Barcelona are under no obligation to offer him a new deal."
Abidal recently resumed match action after a lengthy spell on the sidelines due to a liver transplant and has made four Liga appearances so far this term.
