Thorgan Hazard says he still hopes to have a future at Chelsea just days after completing a permanent move to Borussia Monchengladbach, with the Blues inserting a buy-back clause in his contract in order to keep monitoring his development.

The 21-year-old forward moved to Stamford Bridge from French side Lens just months after his brother Eden made a £32m ($49m) move to west London from Lille in the summer of 2012.

After spending two seasons on loan in his homeland with Zulte Waregem, Thorgan moved to Borussia-Park in the summer of 2014 on a season-long loan deal but at the end of February, Chelsea confirmed his permanent transfer for a fee believed to be around €8m.

"Chelsea Football Club wishes Thorgan well for the future and will continue to monitor his progress," they said.

The 21-year-old starlet said he is focused on thriving at Monchengladbach but revealed he would like to return to Stamford Bridge as a player in the future.

"It is true that Chelsea has a buy-back option. I'm glad, because I hope to still play for Chelsea. That remains a goal," the player told to HLN, according to Kristof Terreur, the UK correspondent of the Belgium newspaper.

"I am focusing on excelling at Borussia Monchengladbach, but I still hope to play for Chelsea one day."

Chelsea manager Jose Mourinho claimed on January that even though it was still too soon for Eden's brother to play at Stamford Bridge, he had the "potential" to do it in the future.

Mourinho said: "He's one of the few players I travel to see play live and we like him very much. But there is here one player in front of him who is not bad, a guy called Hazard like him, but Eden.

"The best decision was for him to go to Borussia and also Bundesliga is a good championship for him to play in and we'll see what happens."

The Belgium international starlet has made 19 Bundesliga appearances this season, five of them as a starter, scoring one goal while netting further three in the Europa League.
