Firmino will leave Liverpool at the end of this season and the Camp Nou has been touted as one of his potential destinations.
But Rivaldo feels game time could be a problem for Firmino if he does join Barcelona.
Rivaldo, while speaking to Betfair, has provided valuable advice for the current Liverpool forward, suggesting: "Following in the footsteps of other great Brazilian players, I believe Firmino would fulfil a dream of playing for Barcelona. However, I think he should first find out what his role in the team would be."
"Xavi always plays with one centre forward - Robert Lewandowski - and the arrival of Firmino could suggest a change of strategy, but will most likely mean that he would be a bench player who would play only a few minutes. That's why I think he should weigh up his decision, not least because he's leaving Liverpool because he's lost his leading role within the club. That does not take away the beautiful history he has written."
"No doubt playing at Barcelona is a dream come true, but at this late stage of his career, he might need to look for another club that gives him greater assurance of playing more minutes. So, should he reach an agreement with Barcelona, I would hope that he talks to Xavi first in order to understand what his role in the squad will be."
