Brazilian World Cup winner Taffarel has backed Fiorentina's Neto to go all the way to the top.
The Serie A star is the subject of reported interest from Liverpool, with his contract expiring in the summer, and him yet to commit to a new deal.
The 25-year-old is at a crucial stage of his career, and is certainly not rushing into a decision.
USA 1994 star Taffarel told Italian website Tuttomercato: "He really has a lot of potential, he a guy who is in a good moment of his career.
"He us playing well, and has trained intensely. He has different qualities, great security in particular.
"I really like his technique, has good feet. He has great possibilities, for Brazil there is great competition."
Neto has helped Fiorentina manage to concede just 11 goals in 12 league games this season. Despite this, they sit in 10th position, and look to have an uphill task to secure European football.
This is only likely to help Neto decide he needs a new challenge, and if Liverpool are, as suggested strongly considering buying him as a free agent addition to provide competition for Simon Mignolet, he could be an excellent choice.
