Cristiano Ronaldo shared a close friendship with Marcelo during his time at Real Madrid.
In fact, the 34-year-old Portuguese footballer trusted him enough to tell him a secret ahead of last season's Champions League final against Liverpool.
Ronaldo told the 30-year-old Brazilian left-back about his future plans, specifically for the fact that he would be heading to Juventus.
"Damn, we were training for the final and he told me: 'I'm leaving,'" Marcelo told Esporte Interativo (via Football Espana).
"I realise that I have lied to you about this before, but that is because I had to.
"Juventus move? They are a great club, but I have a contract with Real Madrid."
Marcelo signed a new contract with Los Blancos back in September 2017, which will keep him at the club until 2022.
Despite the fact that he is contracted with the club, there have been rumblings that the Madrid star would be up for a reunion with Ronaldo at Juventus.
Before the five-time Ballon d'Or winner completed his move to the Italian club last summer, Marcelo broke his silence and said that the Madrid dressing room wanted Ronaldo to stay in Spain.
"Cristiano is not the owner of Real Madrid," he said last year.
"If the president wants to sign someone, the president will sign him. But why can't Neymar come and Cristiano stay?
"The dressing room all wants Cristiano to stay. And Real Madrid's doors are always open for Neymar. Madrid must always look for the best players.
"One day Neymar will play for Real Madrid."
Ronaldo has been relishing the challenge of Serie A and has made 23 appearances for the Old Lady, scoring an impressive 18 times this season.
Will Ronaldo inspire Juventus to the Champions League crown this season?
