In the summer of 2009, Sambueza moved back to Mexico, this time to play with Estudiantes Tecos. He made his Apertura debut on 2 August in a league match against Puebla in a match which ended in a 1–1 draw. Rubens played 15 matches that tournament in total, scoring zero goals, but having three assists. It would not be until the Bicentenario 2010 tournament that Sambueza would score his first goal for Tecos, scoring on a penalty kick in a 1–1 draw against his former team, UNAM, on 14 February. He would go on to be a mainstay in the Estudiantes line-up for the rest of his time at the club, eventually playing his final match on 16 April 2012, when the team was relegated to the second division after 37 years in the top-flight, drawing 1–1 with Puebla, with Sambueza scoring the only goal for Estudiantes.

On 30 May 2012 it was confirmed that Sambueza was transferred to América, reuniting him with his former manager whilst at Estudiantes Tecos, Miguel Herrera. His first match with Las Águilas came on 28 July 2012 in a 4–2 win over Jaguares at the Estadio Azteca. He scored his first goal a week later in a 2–2 draw against Atlante. He scored the following two matches against Atlas and Querétaro in a 1–1 draw and 4–0 win, respectively. He finished his first season with América playing 16 matches, scoring four goals and having three assists. In only his first tournament at the club, Sambueza was named the club's best midfielder by the fans in a social media poll, receiving 50.75% of the votes, ahead of captain Daniel Montenegro.

In August 2008 Rubens moved, on loan, to Flamengo for a period of one year. He was assigned with the number 10 shirt, previously worn by club legend Zico, and vacant after Renato Augusto's transfer to Bayer Leverkusen. On 31 August he debuted for Flamengo as a substitute for Éverton in the Fla-Flu derby, when his club and Fluminense drew 2–2 for the Campeonato Brasileiro Série A.

For the Apertura 2007-2008 tournament, Sambueza was sent on-loan to Mexico side UNAM Pumas, being presented as their number 11, which was worn by legendary player Hugo Sánchez. He debuted in the Primera División against Guadalajara, with the match ending in a 1–1 draw. He played fourteen games in total, providing two assists and scoring two goals that season, against UANL Tigres, and most notably against Pachuca, which led UNAM to the playoffs, eventually losing in the final against Atlante F.C.. The Clausura 2008 tournament saw Sambueza play sixteen matches, scoring two more goals and providing four assists. His loan with Pumas ended and was sent back to River Plate the following year.

Sambueza came up through the youth-ranks at River Plate, making his debut for the first-team on 30 November 2003 in a 2–0 loss against Lanús. He was part of the team that won the Clausura 2004 title. During his time at River Plate, Sambueza played 49 games, scoring three goals.
