Born in Logroño, La Rioja, Viguera graduated from Real Sociedad's prolific youth setup, and made his senior debut with the reserves in 2006–07, in Segunda División B. He played his first match as a professional on 15 September 2007, coming on as a substitute for Iñigo Díaz de Cerio in a 3–2 away win against UD Las Palmas for the Segunda División; he made a further four appearances with the main squad during the following season, as they missed out on promotion by finishing fourth.
In June 2009, Viguera was definitely promoted to Real's first team, but featured rarely as the Basques were crowned champions. On 11 January 2011, he joined Gimnàstic de Tarragona on loan until June, suffering a knee injury the following month that ruled him out for the remainder of the campaign.
On 26 August 2011, Viguera returned to Nàstic again in a temporary deal. After being sparingly used by the Catalans, however, he returned to Real Sociedad on 31 January 2012, and was subsequently loaned to Albacete Balompié in the third level.
On 6 July 2012, Viguera joined neighbouring Deportivo Alavés also in division three. He was an ever-present figure in his first year, scoring 21 goals all competitions comprised to help his team achieve promotion to the second tier in the play-offs.
On 14 August 2013, Viguera extended his contract with the club until 2015. He netted 25 times during the season, as the side narrowly avoided relegation; highlights included a hat-trick at CE Sabadell FC on 8 February 2014, contributing decisively to a 4–0 success.
On 13 June 2014, Viguera signed a three-year deal with Athletic Bilbao for €1 million. He scored his first La Liga goal for his new team on 21 November, netting the second of a 3–1 home win against RCD Espanyol.
On 30 August 2016, Viguera signed a two-year contract with Sporting de Gijón. He scored just once in the league during his first season, which ended in relegation, and featured even less in the following.
