Omar Mascarell

Eintracht Frankfurt On 6 July 2016, Mascarell signed with Eintracht Frankfurt on a three-year contract. His maiden appearance in the Bundesliga took place on 27 August, when he played the full 90 minutes in a 1–0 home defeat of Schalke 04.

Mascarell spent the better part of the 2017–18 season on the sidelines, due to an achilles tendon injury. On 5 May he scored his first goal league goal in a 3–0 win over relegation-threatened Hamburger SV at the Waldstadion. He played the entire final of the DFB-Pokal two weeks later, helping to a 3–1 victory against league champions Bayern Munich; he had opened his account for the club in the quarter-finals by concluding a 3–0 win at home to Mainz 05.

Schalke 04 On 29 June 2018, Mascarell's buy back clause was activated by Real Madrid for €4 million. He was subsequently sold to Schalke 04 also in the German top division for €10 million, signing a four-year contract. From February to September 2020, he was sidelined with an abductor muscle injury, returning for the reserve team's 2–0 Regionalliga home win against SV Rödinghausen.

For 2019–20, Mascarell was appointed vice-captain. 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; however, he was stripped of the armband on 30 January 2021 and replaced by Sead Kolašinac. His one goal in 71 appearances for them was on the same day, opening a 1–1 draw at Werder Bremen.

Elche On 23 August 2021, free agent Mascarell returned to his home country after agreeing to a one-year deal with Elche in the top tier. He totalled 62 games during his spell at the Estadio Martínez Valero, suffering relegation in 2022–23.

Mallorca On 27 June 2023, Mascarell joined Mallorca on a three-year contract. He scored his first goal in the main division on 10 May 2025, equalising an eventual 2–1 home defeat of bottom-placed Real Valladolid; he needed 145 matches to achieve this.

Al-Khaleej On 24 June 2026, after Mallorca's relegation, Mascarell moved to Saudi Pro League side Al-Khaleej.

International career Spain Mascarell is of Equatoguinean descent through his Bubi great-grandmother, while his paternal grandfather was born in the country. He won caps for Spain at under-18 and under-20 levels, also featuring once for the Canary Islands under-18 side.

Equatorial Guinea In May 2012, Mascarell was called by Equatorial Guinea for the 2014 FIFA World Cup qualifiers against Tunisia and Sierra Leone. He travelled to Malabo, 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.

In December 2023, Mascarell was pre-selected for the 2023 Africa Cup of Nations; he did not make the final cut, however. He made his debut on 5 June 2024, in a 1–0 loss away to Tunisia for the 2026 World Cup qualifying phase.
