grand slam champion is the victim of a misunderstanding between the australian government and tennis australia. becker had his own illustrious career as a player before he turned to coaching the world's number-one player. he tells cnn that djokovic's predicament is heartbreaking to watch. take a listen. >> novak is like a family member to me, and i'm struggling. it's unfortunate for him. he's a fine man, and the difference of opinion with many things, but he's a very, very good character. he wouldn't have taken the plane if tennis australia wouldn't have given him the exemption. tennis australia obviously has a misthink with the australian -- misunderstanding with the australian government. and that's why he's in detention. it's terrible for him. imagine this man -- he doesn't drink, doesn't sleep in a normal bed, he looks at life in a different way than most other players, hence he's so successful. for him to be stationed in a room that he's in for the last couple of days just terrible.
