Ancelotti is preparing Los Blancos to face the Sevilla defender in LaLiga on Saturday.
Ramos was a key member of the Madrid squad during the Italian’s first spell between 2013 and 2015.
The defender scored the 93rd-minute equaliser in their 2014 Champions League final win over Atletico Madrid.
Ancelotti said in a news conference on Friday: “I’d love to see [Ramos] and say hello. I have affection for all the players I’ve had, but above all, I have special affection for him.
“If I’m here today, it’s because of Sergio Ramos. If he hadn’t scored the goal in the [Champions League] final, I probably wouldn’t be here. For that, and for everything he did for this club, everybody has a lot of affection for him. He’ll play well, for sure. Let’s hope he doesn’t score, but if he does, he can [celebrate] however he wants!”
