Born in Alicante, Valencian Community, Samuel started his senior career at local Hércules CF, with its reserves.
In 2005 he moved to amateur neighbours CD Alone de Guardamar, being an important unit as they eventually retained their Tercera División status.
On 9 June 2007, courtesy of manager David Vidal, he made his debut with the first team, starting in a 1–0 home win against CD Castellón; he consolidated his position in the 2007–08 season with the club also in the Segunda División, and received abroad offers from England's Sheffield United and Fulham, which eventually died down.
Samuel moved to La Liga in summer 2012, agreeing to a four-year deal at RC Celta de Vigo.
[7] He only appeared once in the competition, after coming on as a second-half substitute for Mario Bermejo – following Gustavo Cabral's second yellow card and subsequent dismissal – in the Galician derby against Deportivo de La Coruña (1–1 home draw);[8] on 30 June 2015, after dealing with a serious anterior cruciate ligament injury to his left knee and also having served second-tier loans at Deportivo Alavés and Real Valladolid, he left Balaídos.
