Omar Mascarell González (born 2 February 1993) is a professional footballer who plays as a defensive midfielder for La Liga club Mallorca.

Formed at Real Madrid, where he made one first-team appearance, he also played in La Liga for Sporting de Gijón, Elche and Mallorca.

Born in Santa Cruz de Tenerife, Canary Islands, Mascarell joined Real Madrid's youth system at the age of 17, arriving from local club Laguna.

[5][6] Mascarell made his La Liga debut with the Merengues on 1 June 2013, replacing Mesut Özil late into a 4–2 home win against Osasuna in what was the last matchday.

[15] He played the entire final of the DFB-Pokal two weeks later, helping to a 3–1 victory against league champions Bayern Munich;[16] he had opened his account for the club in the quarter-finals by concluding a 3–0 win at home to Mainz 05.

After Alexander Nübel decided to leave the club at the end of the season, he was selected by head coach David Wagner as his successor;[21] however, he was stripped of the armband on 30 January 2021 and replaced by Sead Kolašinac.

He travelled to Malabo,[33] but nonetheless declined to play in any of the two matches because he had already appeared for Spain at youth level and did not want to give up on that option; according to the local press, the Equatoguinean Football Federation was completing the administrative procedures of his eligibility.
