Born in Cerrito, Ñeembucú Department, Villar started his career at Club Sol de América where he was coached by legendary Ever Hugo Almeida, also a goalkeeper, as the team also included another player in that position as their coach, Modesto Sandoval.
In 2001, he moved to Club Libertad, where he was reunited with Sandoval: he won back-to-back Paraguayan Primera División titles with the side, in 2002 and 2003, signing the following year with Argentina's Newell's Old Boys.
As an undisputed starter, Villar helped Newell's to the 2004 Apertura championship, also being considered by the press as the Goalkeeper of the Year – previously, he had won the Paraguayan Footballer of the Year award (2004).
In January 2008, terms were agreed upon between Newell's and Real Valladolid of Spain for Villar's transfer, effective in the summer. On 14 July, he was officially presented by his new club; due to starter Sergio Asenjo's injury, he was able to appear in 15 La Liga matches in his first year.
During the 2009–10 season, Villar constantly battled for first-choice status with Jacobo, featuring in 23 games as the Castile and León side returned to Segunda División after a three-year stay. He was released in June 2011 at the age of 34, mainly due to his high salary.
Villar changed clubs and countries again on 18 June 2013, after agreeing to a one-and-a-half-year contract with Colo-Colo in the Chilean Primera División. He helped them win the Clausura in his debut campaign, as first-choice.
Villar represented Paraguay at the 1997 FIFA World Youth Championship, and received his first cap for the full side two years later. He also appeared with the under-23s at the 2000 CONMEBOL Men Pre-Olympic Tournament, making four appearances.
Having been selected for the 2002 FIFA World Cup, backing up José Luis Chilavert, Villar was already a starter in the 2006 edition, but had a brief participation: during the first seven minutes of the opener against England, just after Carlos Gamarra's own goal, he got injured, was replaced by Aldo Bobadilla and subsequently sidelined for the rest of the tournament, in which the national team was eliminated in the first round.
In the 2010 World Cup in South Africa, Villar played all the matches for the eventual quarter-finalists and only conceded two goals, against Italy in the group stage (1–1) and Spain in the last-eight match (0–1, also saving a Xabi Alonso penalty), and was selected as captain. During the 2011 Copa América he was again first-choice and captain, and helped his team reach the final, notably saving a penalty in the quarter-finals shootout against Brazil (0–0 after 120 minutes); he was named the Best Goalkeeper for his displays during the competition, keeping clean sheets in three games.
