Thorgan Hazard is not interested in returning to Chelsea until he has made himself a star at Gladbach, according to the London Evening Standard.
The Bundesliga outfit signed Hazard, the younger brother of Chelsea No.10 Eden, in 2014 in a deal worth £5.9m in 2014.
Having failed to nail down a regular place in the team last season, the 23-year-old has really kicked on this season, fuelling a return to Stamford Bridge and a reunion with his older brother.
Chelsea reportedly have a £12.9m buy-back clause, although Gladbach have denied those reports since.
Hazard has scored more goals than any other Gladbach player in the Bundesliga this season (3).
