Ronaldo and Zidane spent two-and-a-half seasons together with Los Blancos between 2016 and 2018, during which they inspired the club to three UEFA Champions League titles, two FIFA Club World Cup trophies and one LaLiga crown.
Both player and manager left the club ahead of the 2018/19 campaign, with Ronaldo joining Juventus and Zidane taking a sabbatical, although the latter returned less than a year later following Julen Lopetegui and Santiago Solari's respective dismissals.
"...A player that I will never forget is Cristiano Ronaldo," Arjoud added.
"I like respect and discipline. He embodies that. Do I dream of signing him for Marseille? Everything is possible in life. He is generous and gives a lot.
"It makes me vibrate. It would be a dream to have him in Marseille but that is the task of [potential future club president] Mourad Boudjellal [to make it happen]."
