Belgium coach Roberto Martinez admits he is concerned about Eden Hazard at Real Madrid.

Hazard's international coach, though, doesn't think it's something to worry about.

"It doesn't worry me in the long run," Martinez stated, "I'm concerned about the lack of happiness that he cannot have at the moment.

"Eden should be on the pitch and able to enjoy his football. Unfortunately, now we have to wait a little longer, but we have no long-term concerns.

"We would be concerned if we didn't know Hazard and if he wasn't reacting to the treatment."
