## Club career

Marcos was born in Sacedón, Province of Guadalajara, Castilla–La Mancha, and graduated from Atlético Madrid's youth academy. He made his debut as a senior with the reserves in the Segunda División B.
In summer 2012, Marcos moved to another reserve team, Villarreal CF B also of the third division. He was appointed their captain at the start of the 2014–15 season.
Marcos first appeared with the main squad in competitive matches on 15 February 2015, starting in a 2–0 La Liga away loss against Rayo Vallecano. On 9 July, he was loaned to Segunda División club CD Lugo in a season-long deal.
Marcos scored his first professional goal on 8 November 2015, the game's only in a 1–0 away victory over Girona FC. On 21 July of the following year, he was transferred to Real Valladolid also in division two after agreeing to a three-year contract; midway through the 2017–18 campaign, he left for fellow second-tier side Cultural y Deportiva Leonesa.
In June 2021, Marcos signed for Racing de Santander. Having achieved promotion to the second division in his only season, contributing 27 games but only starting six, he automatically renewed his contract; shortly after, however, he was deemed surplus to requirements by new manager Guillermo Fernández Romo and left.
Marcos subsequently dropped down to the Segunda Federación, where he represented Hércules CF and CD Guadalajara.
