Liverpool are keeping tabs on Real Madrid's Mesut Ozil after Jose Mourinho gave the German an ultimatum, according to the Sunday People.
Mourinho has reportedly told the 23-year-old to buck up his ideas after some inconsistent performances of late.
Real paid Werder Bremen £12.4million for Ozil after he starred in the 2010 World Cup.
Ozil recently praised the Portuguese coach for his influence.
