The 26-year-old, who is the younger brother of Chelsea’s Eden Hazard, has been linked with Liverpool, Atletico Madrid and Borussia Dortmund.
And the race is on after Hazard told Borussia Mönchengladbach sporting director, Max Eberlm that he wants to quit the Bundesliga club this summer.
Gladbach were keen to extend Hazard’s contract which runs until 2020, but he has turned down the offer
Eberl told Sky Germany:
“Thorgan has informed us that he doesn’t want to extend his contract and that he wants to leave the club in the summer to take the next step.
“I’ve heard this statement 15 times in the last 10 years as really great players have left us. That’s the way it is for us.
“We’ll have to see where his path will continue. I don’t know whether it will be at BVB (Borussia Dortmund), who are constantly being mentioned, or at Atlético Madrid, Liverpool or another club.”
Hazard has scored nine goals in the Bundesliga this season and has provided 11 assists.
He joined Gladbach from Chelsea for £7.2m in 2015.
