Hazard, the brother of fellow Chelsea star Eden, arrived at Stamford Bridge from Lens in 2012 - shortly after the Blues had confirmed the capture of his older sibling. Yet with a number of attacking midfield players already at the club, Hazard became the latest Blues youngster to be farmed out on loan in order to gain first team experience.
The 21-year-old spent two seasons on loan with Zulte Waregem in his native Belgium, racking up 17 goals and 20 assists in his second season with the club. His exploits in Belgium had unsurprisingly attracted interest from other European clubs, who were looking to take Hazard on loan with a number of playmakers still in West London with Jose Mourinho's men.
A handful of Bundesliga teams wanted to bring Hazard to Germany, yet speculation over the last few days has suggested that it's Borussia Monchengladbach who will land his signature - and today it was confirmed that Chelsea will loan Hazard out to Lucien Favre's side for the next year.
"Thorgan is a promising talent. He can play across several positions in attack and we're happy that he's decided to take the next step in his career at Borussia," said Gladbach sporting director Max Eberl.
The hope now is that Hazard will develop in the Bundesliga, much like his compatriot Kevin de Bruyne did with Werder Bremen before coming back to Stamford Bridge. However, Mourinho will no doubt be looking for Hazard to make more a long-lasting impact at Chelsea than de Bruyne did, after he was sold to Wolfsburg in January.
Gladbach allowed Venezuelan midfielder Juan Arango to leave the club this summer, meaning Hazard should see plenty of first team football, but will be competing with the likes of Patrick Herrman and new signing Andre Hahn.
