Menéndez was born in Gijón, Asturias. A product of Sporting de Gijón's prolific youth academy who started playing as a left winger, he made his senior debuts in the 2010–11 season, appearing in 21 games in the third division for the reserves, who initially suffered relegation but were later reinstated.
Menéndez first appeared officially with the main squad on 13 December 2011, featuring the full 90 minutes in a 1–0 away win against RCD Mallorca for the campaign's Copa del Rey. On 1 May of the following year he made his La Liga debut, again playing the entire match in a 2–3 home loss to Villarreal CF that all but signified the first team's relegation after a four-year stay.
On 13 August 2013, Menéndez signed a new three-year deal with the club. In the 2014 summer he was definitely promoted to Sporting's first team, now in Segunda División, being assigned the no. 3 jersey.
Menéndez scored his first professional goal on 20 September 2015, netting the winner in a 3–2 away success against Deportivo de La Coruña. His second came two rounds later in another away fixture that ended in win, 2–1 at RCD Espanyol.
