Ozil has been one of the Gunners’ star performer’s this season having provided 19 assists and seven goals in 36 appearances.
The 27-year-old was one of the stars of the show last weekend despite the Gunners 2-1 defeat to Watford in the FA Cup.
The defeat was Ozil’s first in the FA Cup since joining Arsenal on a record £42.5 million move from Real Madrid in 2013.
Arsenal are in need of a miracle after suffering a disappointing at the hands of the La Liga giants at the Emirates.
Barcelona recorded a 2-0 win with both goals coming from Leonel Messi.
