talkSPORT's man in Spain, Graham Hunter, claims Manchester United will have to watch Mesut Ozil, along with Cristiano Ronaldo, during their Champions League last-16 first leg tie against Real Madrid.
The European giants will meet at the Bernabeu on Wednesday night and Hunter, who has followed La Liga for a number of years, claims Sir Alex Ferguson's men will have to wary of the German.
He said: "He knows how to drift into space and open up defences. Unless Man United find a way to close him down then they'll have a problem on their hands at the Bernabeu."
