Robredo's favorite foods are fish and other seafoods, particularly sushi and sashimi; he also is fond of sweet things and was formerly sponsored by the European sweets company HARIBO. He is currently sponsored by Sergio Tacchini for his sportswear, Dunlop for his tennis racquets, TW Steel watches, and the Ukrainian Food Company.
Robredo is known for his patrician good looks and a gentle, quiet personality; he readily admits to being a homebody. His native languages are Spanish and Catalan, and he also speaks English and French.
In May of 2006, Robredo publicly stated that he was no longer in a relationship with Argentinian tennis player Gisela Dulko. They had been dating for about a year.
Some fans refer to Robredo as "Disco Tommy" for the long, wavy hairstyle he began cultivating during the 2006 tennis season; after Robredo mentioned that he calls his coach "President Palmer" while his coach calls him "Jack Bauer" (from 24), fans also began referring to him as "Disco Jack."
2007 marked increased media exposure for Robredo. Besides posing nude for the July issue of the UK edition of Cosmopolitan, he was also recognized by the Spanish editions of Men's Health and Marie Claire, as well as People en Español.
As a junior player, Robredo won the Junior Orange Bowl 16-Under in both singles and doubles (with Marc López) in 1998. As a professional he made the singles and doubles finals of a Futures-level event, winning the doubles title with Pedro Cánovas. In 1999 he made the semifinals of the boys' event at the French Open and won a Futures tournament in singles as well as another in doubles. Earlier that year in Robredo's hometown tournament of Barcelona - his first event at the ATP Tour level - he recorded a fantastic win over Marat Safin, who was then ranked in the world's top thirty, before going on to lose to top ten player Todd Martin.
2001 was a breakthrough season for Robredo: He reached his first final at the ATP Tour level in Casablanca and won his first title on the main tour in Sopot. He also made the fourth round at two Grand Slams, losing to Yevgeny Kafelnikov at the French Open and winning a fantastic five-set match against world number five Juan Carlos Ferrero at the U.S. Open before losing to Andy Roddick. Robredo also made the semifinals of three other tour events, and by the end of 2001 he was the second youngest player to end the season inside the world's top thirty, behind Roddick.
Arguably, the highlight of Robredo's 2003 season was his run to the quarterfinal of the French Open. Robredo's result was notable in that he took out world number one Lleyton Hewitt in five sets and three-time French Open champion Gustavo Kuerten before eventually falling in a second five-set match to defending champion Albert Costa. Robredo remarked before his match against Costa: "I've beaten the ace, I've beaten the king," in reference to his wins over Hewitt and Kuerten. "Now I need to beat the jack, don't I? If I beat Costa, I'll have beaten the entire pack of cards. Despite not reaching a quarterfinal in any Masters Series event this season, strong showings in other tournaments, including three quarterfinals, three semifinals (one of which was a second Båstad semifinal), and a runner-up result in Stuttgart allowed Robredo to break into the world's top twenty for the first time in his career.
In 2007 Robredo reached the quarterfinals of the Australian Open for the first time, losing to world number one Roger Federer. Although no one at the tournament managed to win a set from Federer, Robredo and the eventual finalist Fernando González tied for the most number of games won against the world number one. He went on to lose another quarterfinal to Federer at the French Open; in that match Robredo became the first man since Andy Roddick in the 2006 U.S. Open to win a set from Federer in a Grand Slam tournament, snapping Federer's record winning streak of thirty-six consecutive sets in Grand Slam matches. Robredo later won his first title of the year by beating José Acasuso in straight sets at Sopot, the tournament where he had won his first ATP Tour title six years earlier.
2007 brought increased hardcourt success for Robredo: After years of contesting finals on red clay he reached the final of a tournament played on hardcourts for the first time at Auckland, followed by two more hardcourt finals at Beijing and Metz. He won the Metz title, defeating Andy Murray in three sets for his second title of the season. Despite reaching the semifinal of Estoril and six quarterfinals (including three Masters quarterfinals) in 2007, Robredo also lost his opening match at numerous events: At Dubai; at the Hamburg Masters and the Swedish Open where he was defending champion; and at three other Masters tournaments. He ended the year ranked #10 in the world - too low to compete at the TMC but high enough to attend as an alternate.
Robredo has had some doubles success this season, teaming up with compatriot Rafael Nadal to win his first doubles titles in four years by beating Mahesh Bhupathi and Mark Knowles at the Monte Carlo Masters. He also reached the semifinals of the Hamburg Masters with Leander Paes. Bhupathi, Knowles, and Paes are all former world number one doubles players.
