Romero made his debut for Vélez Sársfield in 2012 at 18 years of age, coming on as a substitute in a 0–0 draw with Estudiantes de La Plata. In his first season with the first team, Romero helped Vélez to win the 2012 Inicial championship, playing 13 games (including 4 as a starter replacing injured Francisco Cerro). The midfielder also entered the field in Vélez's victory over Newell's Old Boys for the 2012–13 Superfinal and was a starter in his team's victory over Arsenal de Sarandí for the 2013 Supercopa Argentina. In 2016, Romero was transferred to Cruzeiro Esporte Clube.
After a difficult start to his Cruzeiro career, Romero began gaining a lot of attention for his versatility playing in many different positions. Lucas Romero then became part of the first 11 playing either as a right-back or on his main position of defensive midfielder.
