Having previously found themselves on opposite sides of a Clasico divide in Spain, the pair have locked swords at regular intervals.
Their rivalry was recently rekindled in a European showdown between Madrid and Paris Saint-Germain, with Dani Alves accused of wiping snot on an old adversary.
The Brazilian has strenuously denied those allegations and reiterated that his personal battle with Ronaldo has been overplayed, telling Esporte Espectacular: "It is part of the game, heat of the moment, part of football and nothing personal."
He added on the accusations levelled at him following his latest meeting with Ronaldo: "Thank God that my son does not like football, because football is losing the essence which made me want to be a player.
"Look at the game with Real Madrid, for example. They have said that I put snot on Cristiano's shirt. Is it me or are the people saying these things three years old? It's stupidity without limit."
PSG came unstuck against Ronaldo and Real over the course of two legs, with a 5-2 aggregate defeat seeing the French side fall at the last-16 stage of this season’s Champions League.
Their cause was rocked by an untimely injury to €222 million superstar Neymar ahead of the second leg of that continental contest, with the Brazil international having been forced to undergo surgery on a broken metatarsal.
Dani Alves is among those to have been credited with luring a fellow countryman to Paris in a record-breaking deal, but he has once again played down such claims.
He said: "People think that Neymar is a puppet, but children grow up and make their own decisions.
“He is growing, maturing and learning to deal with difficult moments."
Like Neymar, Dani Alves claims his decision to join PSG was driven purely by sporting ambition, although the 34-year-old concedes that the money in football, from which he and his team-mates are benefiting, has spiralled out of control.
The legendary full-back added: "I came to PSG for the sports project, for how they have valued me as a footballer.
“But if I am very honest, I do not think my salary is in line with my value - it is too much."
