Manchester United boss Sir Alex Ferguson is monitoring Mesut Ozil's situation at Real Madrid according to El Mundo Deportivo.
The Spanish newspaper reports how the 23-year-old German international has struggled for form at the Bernabeu this season, and Los Blancos manager Jose Mourinho has warned Ozil he must improve.
Real are demanding better from the attacking midfielder, and their management team have revealed he is on trial until the end of the campaign - and say he could be sold in June.
Ferguson expressed an interest in bringing Ozil to Old Trafford last year before he made his switch to La Liga, and the Red Devils chief is still keen on securing his signature.
Manchester United have injury problems with yesterday's announcement that Darren Fletcher will take some time away from the game, and with Tom Cleverley and Anderson both on the sidelines, the reigning Barclays Premier League champions are short on midfield options.
Ozil could help solve the club's creative concerns in the middle of the park, and may attempt to engineer a deal when the transfer window reopens in January - but failing that could make a cut-price offer at the end of the season.
