In August 2007, Real Madrid signed Bueno on a professional contract with the first team. He was called up to the pre-season training under coach Bernd Schuster, teaming up in a friendly with FC Lokomotiv Moscow where he was replaced at half-time by another cantera player, Javier Balboa.

On 11 November 2008, due to many injuries to the main squad, Bueno was given his official debut, in a Copa del Rey home contest against Real Unión (third level): within minutes of his entry, 15 minutes into the second half, he scored in a 4–3 final win, but Real Madrid suffered a shock exit from the competition (6–6 aggregate). Eleven days later he made his La Liga debut, replacing Raúl late into a 1–0 home success over Recreativo de Huelva.

On 15 July 2009, Real Valladolid purchased Bueno on a five-year deal, with Real Madrid having an option to repurchase during the first two. During his first season he was used intermittently, as the Castile and León side also suffered top flight relegation.

On 30 August 2010, English club Derby County announced that Bueno was a guest at the Rams’ 2–2 draw against Queens Park Rangers, and that a loan deal was very close to being completed in time for the close of the transfer window. It was revealed the following day that the player signed on a season-long loan.

Bueno signed with Rayo Vallecano in the summer of 2013, for two years. On 28 February 2015, he scored four goals in only 14 minutes in a 4–2 league home win over Levante UD, being the second fastest to accomplish this feat after Bebeto in 1995.

On 25 May 2015, free agent Bueno signed with FC Porto for five years, joining a host of compatriots at the Portuguese club including manager Julen Lopetegui. He spent most of his first season on the sidelines, due to a meniscus injury.

On 31 August 2016, Bueno returned to Spain and its first division after agreeing to a one-year loan deal at Granada CF. He scored his only goal for the team on 16 September, in a 2–2 draw at neighbouring Real Betis.

Bueno went back to his hometown on 31 January 2017, as he joined CD Leganés halfway through their debut top-flight campaign. Mostly used as a substitute, he only scored in a 4–0 home win over Deportivo de La Coruña on 25 February, as relegation was avoided.

On 26 January 2019, Bueno was loaned across the city to Boavista F.C. until the end of the season, and scored a free kick in a 3–1 home win over C.D. Feirense on his debut on 2 February. In an interview with Radio Marca in his homeland the following month, he accused his parent club of workplace bullying.
