Thorgan Hazard admits he felt it was "too early" for him to play for Chelsea after sealing a permanent move to Borussia Monchengladbach.
The Bundesliga side confirmed the permanent transfer of the the 21-year-old on Monday (23 February) for a fee believed to be around €8m.
Following the announcement of the deal, Chelsea quickly confirmed they had included a buy-back clause on the Belgian's deal, but Hazard believes he is still not at the level required to break into the first team at Stamford Bridge.
"I have signed here for four years with the option of a further year, because I think Borussia are the right club for me to continue developing at," Hazard told Monchengladbach's official website.
"It is too early for me to play for Chelsea still, Borussia are the club that suits me the best at the moment. Monchengladbach is located not far from Belgium and the club has great supporters – the fans are incredible.
"The team are good, the head coach is great and it is the best place for me to be."
Before making his decision, Hazard spoke of his desire to find "stability" in his career despite still dreaming of lining up alongside his older brother Eden for Chelsea and being tipped for great things by Jose Mourinho.
And the attacking midfielder believes he has found that stability at Monchengladbach.
"Of course, you only sign a deal of this length when you feel at home somewhere, which is certainly true in this case. Consequently, I decided to sign here.
"I want to play for the same club for a number of years and I feel that will be the case here."
Hazard was snapped up by Chelsea from French side Lens months after his brother sealed his lucrative move to west London from Lille in 2012. He did not make a single appearance at the club, having also spent last season on loan back in his homeland with Zulte Waregem.
