At the beginning of the season he was known as just the 'kid brother' of £32 million man Eden Hazard, but there was enough about him for Chelsea to spend an additional couple of million on signing him up too.
He spent barely a month at the Blues before being sent out on loan to Jupiler Pro League side Zulte-Waregem, and Hazard has helped transform them from a mid-table side to challengers for Belgium's top honour.
Zulte are currently going toe to toe with perennial challengers Anderlecht in the play-offs, after securing a top four place to battle it out for the title.
And for his contribution to that, Hazard is becoming a big star in his own right, earning call-ups to Belgium's under-21 side.
Signed from Lens last summer, Thorgan Hazard is now 20-years-old, and plays on the left-wing. For his loan side he has scored three goals, and provided seven assists.
This week he conducted an interview with Belgian publication Sport Magazine, which was glowing in it's praise of the player.
Their article described the younger Hazard as 'one of the great discoveries of the season', while the player himself said: "At Zulte-Waregem, I have showed who I am."
The interview is interesting reading, and let us cut to the chase regarding his future, like fellow loanees he is unclear as to what Chelsea want to do with him, obviously because of the unclear manager situation.
He said: "Today, I do not know absolutely what will happen my future. I belong to Chelsea and it is for them to decide. On the field, I am aware that I must be more decisive, score more goals and give more assists."
It does sound from that like he is open to whatever the Blues suggest, and that includes another loan spell away. It's possible Chelsea may ask him to go on loan to another club in another league to test himself at a higher level.
His experience of Chelsea so far is very limited, with him accepting he was never likely to be there long last summer.
"I stayed for a month which I trained two with both the first team and the rest of the time with the reserves. I knew very well that I was passing through."
