In January 2012 he moved to Red Bull Salzburg, where he won four league and cup doubles, also finishing as the Austrian Football Bundesliga's top scorer three times; he totalled 172 goals in 202 matches for the latter club.

[3] Soriano spent the second halves of that and the following campaigns serving Segunda División loan stints, after which he returned to the Estadi Olímpic Lluís Companys, scoring twice in 24 appearances during the season, incidentally in both 1–0 victories over Getafe CF.

[4][5] In late January 2009, Soriano moved again on loan (and in the second tier), joining Albacete Balompié until the end of the campaign and being released by Espanyol after this spell, his contract not having been renewed.

[7] He made his official first-team debut on 28 October 2009, playing the dying minutes of the 2–0 win at Cultural y Deportiva Leonesa in the round of 32 of the Copa del Rey (7–0 on aggregate).

[10][11][12] This tally gave him the division's Pichichi Trophy,[13] and in the process he eclipsed the club's previous record for most goals by a player in a single season, which was 15 by Martín Domínguez in 1987–88.

[19] Soriano was sent off on 17 July 2012 in a 1–0 loss at F91 Dudelange, having played only 37 minutes as a substitute for Gonzalo Zárate in the first leg of the second qualifying round of the UEFA Champions League.

[20] He struck 26 goals in 32 games over the league season, including a hat-trick on 20 April 2013 in a 6–2 win against Wolfsberger AC; that morning, he witnessed his wife Cristina Sabater giving birth to their daughter.

[24] In the round of 32, he grabbed a brace in a 2–0 win at AFC Ajax,[25] and despite the team exiting in the next stage, he was the tournament's top scorer with eight goals, only the second Spaniard to do so after Rayo Vallecano's Bolo in 2000–01.

[34] He arrived at the century mark in 113 games, quicker than national icons Hans Krankl and Toni Polster,[35] and by the following March he had achieved 150 goals in 170 matches across all competitions; manager Óscar García stated: "He is the best footballer I have ever worked with.

[19] For the third successive year, Soriano was the top scorer as his team won the league, and he scored three times in a 5–0 win over FC Admira Wacker Mödling in the cup final to seal another double.
