The France international hopes to see his former Blaugrana teammate make the move to Ligue 1, while he has stressed he has nothing but fond memories of the Catalans.
The 31-year-old Blaugrana shot-stopper recently announced his decision to leave Camp Nou when his contract expires at the end of the season. Consequently, Abidal is hoping that Valdes decides to follow in his footsteps by making the move to the French principality.
"Monaco would be a good option for Victor if we play in the Champions League next season," Abidal told Cadena COPE.
The Frenchman, who left Barca for Monaco this summer, then briefly reflected on his time in Catalunya and stressed that he has nothing but fond memories of his spell with the current Spanish champions.
"I am not disillusioned with Barcelona," Abidal said. "I understand the club's decision to let me go. I have a lot of respect for Barcelona and have never said anything bad about the club. I am very happy to have been at Barca for six years."
Abidal won four Liga titles during his time at Barcelona, while also lifting the Champions League twice.
