The veteran Brazilian defender left Barca for a second time this summer to join Liga MX club UNAM.
He made 405 appearances during his time at the Nou Camp, scoring 22 goals whilst providing 104 assists.
During the height of his career, he came up against Ronaldo when Barca clashed with Real Madrid in the El Clasico.
Ronaldo, formerly of Madrid, forged an eye-catching rivalry with Alves during his time at the Santiago Bernabeu.
Not only did the two legendary players duel for their clubs but also on international duty and Alves has uploaded a picture of the pair on his Instagram, saying:
“When we were friends!! Come here my little friend.”
Whilst Cristiano Ronaldo can lay claim to being one of the greatest players in history, Alves eclipses the former Galactico in one department.
The Brazilian is the most decorated player in not only Barca’s history but in football as a whole, winning 43 trophies to Ronaldo’s 30.
The pair are unlikely to ever face off against each other at club level again with Alves having joined the Mexican league.
However, Alves is still in contention to make Brazil’s 2022 FIFA World Cup squad in what will likely be his and Ronaldo’s last international tournament.
The former Barcelona star is now 39 whilst the current Manchester United striker is 37.
