Both Belgian internationals are currently on the books of Premier League side Chelsea, and although 24-year-old Eden is the Blues' key man, younger brother Thorgan is waiting for his first appearance.
The 21-year-old signed for the West London club at the same time as his brother, before immediately heading out on loan to Belgian Jupiler Pro League side Zulte Waregem, where he enjoyed a productive spell. 73 games brought a return of 19 goals for the attacking midfielder, as well as the Belgian Golden Shoe in January 2014 and the award for the best Belgian professional football player in May that year.
He returned to Stamford Bridge over the summer, before agreeing to depart on loan for another campaign, signing with Bundesliga side Borussia Monchengladbach, with whom he has currently made 15 league appearances - scoring one goal.
Thorgan is said by HLN to be keen on securing a permanent switch to Germany having enjoyed his time with the club, but there is one dream to fulfil in his career that could see him remain at Chelsea for the long-run - to play alongside his brother during a competitive game.
As reported by HLN, Hazard has dreamed of playing alongside Eden for Chelsea, and he reaffirmed the possibility of such an event in an interview with the Belgian media outlet - even if it cannot occur with the Blues.
The 21-year-old said: “I'm still a Chelsea player, so it's still possible. But it may also occur with the Red Devils [the Belgian national team].
“We will succeed, if necessary at the end of our career, when we are old men.”
Although Hazard has been tipped to trade Chelsea for Gladbach permanently, he appears to keep faith that a route into Chelsea’s first-team can occur, telling the press that Jose Mourinho is said to hold the youngster in high regard.
He continued: “My father will conduct the interviews with Mourinho. From what I hear, he appreciates me. He personally came to Zulte Waregem to see me - this says a lot.”
