Manchester United boss Sir Alex Ferguson is monitoring Mesut Ozil's situation at Real Madrid.

Ferguson expressed interest in Ozil last year before he made the summer switch to Real.

The Germany international has struggled for form this season and El Mundo Deportivo says he has been warned by Real management he's on trial to the end of the campaign.

Real are demanding better from Ozil and if his form does not improve, they'll seriously consider selling him in June.

Ferguson would love to bring Ozil to Old Trafford to solve his creativity concerns in midfield.
