While removed from the manager's position, Henry is yet to be sacked.
Hazard said of his former Belgium assistant coach: "I feel with him.
"Henry does not deserve this. He has done a good job with the national team. Monaco just did not do well this season. He immediately ended up in an emergency situation. He tried to straighten the crooked situation, but failed.
"Thierry Henry already has my support. I do not worry. I am sure that he will become a top coach in the future. He is always welcome. If he wants to return to the Rode Duivels, he knows where to find us. Voilà."
