After starting his career with Cerro Porteño in his homeland and NEC in the Dutch Eredivisie, Barreto spent the vast majority of his career in Italy's Serie A. He made over 260 appearances in the competition, in service of Reggina, Atalanta, Palermo and Sampdoria
Barreto earned 60 caps for the Paraguay national team from 2004 to 2011. After winning a silver medal at the 2004 Olympics, he played for the country at three Copa América tournaments and two FIFA World Cups, finishing as runner-up in the 2011 Copa América.
In the summer of 2007, Barreto agreed to a four-year contract with Reggina Calcio. He played an integral part in keeping Reggina in Serie A at the end of the 2007–08 season, earning a reputation for scoring long range goals. In summer 2009, after Reggina moved to Serie B, he was sold to Atalanta Bergamo.
At Atalanta, Barreto missed most of his first season through injury, only returning in the last days of the season and not being able to avoid the relegation of his club in Serie B. His excellent performances in Serie B afforded the interest Napoli during the January market. He contributed to the promotion of the Bergamaschi to Serie A in the 2010–11 season, at the end of which he was voted into "Top 11 Serie B" players team by Italian journalists.
During an interview in July 2017, Barreto affirmed that he would not return to Paraguayan football due to family reasons, although he recognized that his time at Cerro Porteño was fundamental for his career.
In May 2020 he agreed the termination of his contract with Sampdoria.
Upon Barreto's contract termination with Sampadoria, NEC's fans had dreamed and expressed his return. Barreto actually owned a house and three apartments that he leased in the city of Nimega, which was also a destination venue for his family during vacations and, on more than one occasion, Barreto manifested his wish to return to the club. NEC's fans had placed a banner at the entry of the club's stadium asking Barreto to return as NEC's General Manager, Wilco van Schaik, lifted the fan's hopes of Barreto returning to the club. Wilco van Schaik had told Holland newsaper Voetbal International that Barreto's name was creating something in the city, that he really is a hero who left something good in there and that he is a good guy who never forgot about NEC, expressing interest in the player since the month of May.
On 15 July 2020, on his 36th birthday and after 13 years in Italian football, Barreto returned to his first European club NEC Nijmegen in Holland's second-tier after 13 years. Barreto signed a season-long contract with the option of extending for another season.
The club's General Manager von Schaik also mentioned that when NEC found out that Barreto was open to a return to the club that they then made contact with him immediately.
Barreto debuted for the Paraguay national football team in a 1–0 win over Costa Rica on 8 June at the 2004 Copa América. He played all four games as his team reached the quarter-finals. Weeks later, he was part of their squad that took home a silver medal at the 2004 Olympics in Greece.
On 17 August 2005, Barreto scored his first international goal to open a 3–0 friendly win over El Salvador in Ciudad del Este. Coach Anibal Ruiz called him up for the 2006 FIFA World Cup in Germany.
At the 2007 Copa América in Venezuela, Barreto again played all four matches of a quarter-final finish. He scored to open a 3–1 win over the United States in the group stage. At the 2010 FIFA World Cup in South Africa, he came on in the 75th minute against Japan in the last 16 and scored the first attempt in the penalty shootout, as Paraguay advanced to the next round for the first time.
Barreto was also in Gerardo Martino's squad that came runners-up to the hosts at the 2011 Copa América in Uruguay. Again on as a substitute in the quarter-finals against holders Brazil, he took the first penalty after another goalless draw, sending it wide in an eventual triumph.
On 5 August 2012, Barreto announced his international retirement for the Albirroja. He said that he could no longer combine the long journeys with competing in Serie A.
