In 2017, he joined Spanish club Las Palmas, but was released by the club at the end of the season. After a year without a club, he announced his retirement in 2019.
 Passage 2:In August 1914, Luxemburg, along with Karl Liebknecht, Clara Zetkin and Franz Mehring, founded the Die Internationale ("The International") group which became the Spartacus League in January 1916. They wrote illegal anti-war pamphlets pseudonymously signed Spartacus after the slave-liberating Thracian gladiator who opposed the Romans. Luxemburg's pseudonym was Junius, after Lucius Junius Brutus, founder of the Roman Republic. The Spartacus League vehemently rejected the SPD's support in the Reichstag for funding the war, and sought to lead Germany's proletariat towards an anti-war general strike. As a result, Luxemburg and Liebknecht were imprisoned in June 1916 for two and a half years. During imprisonment, Luxemburg was twice relocated, first to Posen (now Poznań), then to Breslau (now Wrocław). smuggled out and illegally published her articles. Among them was The Russian Revolution, criticising the Bolsheviks, presciently warning of their dictatorship. Nonetheless, she continued to call for a "dictatorship of the proletariat", albeit not of the one party Bolshevik model. In that context, she wrote the words "Freiheit ist immer die Freiheit des Andersdenkenden" ("Freedom is always the freedom of the one who thinks differently") and continues in the same chapter: "The public life of countries with limited freedom is so poverty-stricken, so miserable, so rigid, so unfruitful, precisely because, through the exclusion of democracy, it cuts off the living sources of all spiritual riches and progress". Another article written in April 1915 when in prison and published and distributed illegally in June 1916 originally under the pseudonym Junius was Die Krise der Sozialdemokratie (The Crisis of Social Democracy), also known as the Junius-Broschüre or The Junius Pamphlet.
