Valero was born in Madrid, and began his football career as a youngster in the ranks of Real Madrid. He made his first appearance for the B-side in Segunda División B as a second-half substitute, took part in the playoffs to earn promotion and played two full seasons in Segunda División.
Valero played only twice for the first team: given his debut by Fabio Capello against Écija on 25 October 2006, replacing Javi García after 60 minutes of a match for the Copa del Rey, he also featured once in the UEFA Champions League, substituting Miguel Ángel Nieto in a 2–2 away draw with Dynamo Kyiv in the group stage.
In August 2007 Valero signed a five-year contract with Mallorca, following his release from Real Madrid. He scored his first La Liga goals in a 7–1 home win over Recreativo on 9 March 2008, and added another a month later, against his former team in a 1–1 home draw.
On 11 May, Valero scored the first goal for Mallorca as they came back from 2–0 down to beat Barcelona in Frank Rijkaard's last home game as the latter's manager. He made 17 starts and played a total of 1,892 minutes during the season to help the club finish in seventh position.
In mid-August 2008, Mallorca's president stated that the club had rejected bids from English club West Bromwich Albion for Valero and Óscar Trejo, but a week later, Valero signed for the club – newly promoted to the Premier League – for a club record fee of €7 million (£4.7 million). He agreed a four-year contract with the option of a further year in the club's favour.
Valero made his debut four days later in Albion's 1–3 League Cup defeat away to Hartlepool United. Manager Tony Mowbray said that he would have benefited from his first game in English football, only hours after receiving international clearance, despite the defeat.
Following Albion's relegation to the Championship after just one season, Valero said that he intended to remain at the club: "I still have a three-year contract here and would like to be true to that. For sure playing in the second division is not ideal. But if I have to put up with it then I am going to put up with it." By the beginning of the next campaign, however, he had changed his mind: "I prefer to play in Mallorca and not to be in the second division in England. This is clear. I am disposed for a loan return but it is necessary for an accord between the clubs".
Just hours before the close of the transfer window, Valero returned to Mallorca on loan for the 2009–10 season. On 13 September, in the first match in his second spell, he scored the club's 1000th top level goal in a 1–1 draw at Villarreal. In another away fixture, he netted in the last minute for nine-man Mallorca to clinch a 1–1 draw against Atlético Madrid in October, and was ever-present as Mallorca finished fifth and qualified for the UEFA Europa League; he also won the prestigious Don Balón Award for the best Spanish player in La Liga.
At the end of the season, Valero returned to his parent club after Mallorca confirmed they could not afford to take up the agreed fee of £2.5 million to make the move permanent.
For 2010–11, it was reported that Valero was joining Villarreal on a five-year contract, but the clubs eventually agreed on a season-long loan, with the move to be made permanent at the end of the season. He scored on his home debut for the team, a 4–0 win against Espanyol on 12 September 2010, and featured heavily throughout the season as the club finished in fourth position and qualified for the Champions League.
On 1 July 2011, Villarreal signed Valero on a permanent basis for an undisclosed fee. Villarreal were relegated at the end of the season, and it was reported that he was among a number of players expected to leave.
On 1 August 2012, Fiorentina agreed with Villarreal for the transfer of Valero. The move was confirmed three days later, and he joined the Serie A team alongside teammate Gonzalo Rodríguez; after joining he said leaving his previous club was not easy, and that he still had not come to terms with its relegation.
Valero made an immediate impact at the Viola, scoring five league goals in 37 games in his first season and providing 11 assists as the team qualified to the Europa League. He scored his first goal in 2013–14 on 15 September in a 1–1 home draw against Cagliari, and, on 2 November, contributed to a 2–0 success at Milan; subsequently, he was named in Goal.com's Serie A Team of the Season.
Valero represented the Spain under-19 team at the 2004 European championships. In the final, against Turkey, he entered the match as an 85th-minute substitute and, two minutes into stoppage time, scored the only goal of the game.
On 4 June 2011 Valero made his debut for the full side, against the United States in Foxborough, Massachusetts. He replaced David Silva in the second half, and assisted Fernando Torres in the last goal.
