Sporting midfielder Adrien has revealed he had the chance to join Chelsea as a teenager - but believes he made the right choice by turning them down.
The French born midfielder has represented Portugal at every age level although he's yet to make his debut for the senior team.
As a youngster in the Sporting youth team, he was one of the most highly rated youngsters in Europe and he had Chelsea scouts watching him closely.
While most of the onlookers now train their attention on teammate William Carvalho, Adrien has admitted that there was serious Premier League interest in the past.
But he turned it down because he was settled in Portugal.
He told Portuguese newspaper Record: "It was very early in my career, I was 16. I wanted to stay and also talked to my family, who advised me accordingly.
"We felt it was better to stay here at Sporting, which has the best training in the world. Fortunately it was the right decision."
Adrien retains hope of making Paolo Bento's Portugal squad for the World Cup this summer, and he played under Bento when he was manager of Sporting. But he faces stiff competition for places in his preferred central midfield position.
Chelsea have one of the best youth teams in the world, and they recently won the FA Youth Cup for the second time in the last three years. The Stamford Bridge club are active when it comes to attracting the world's most talented young players, having brought in the likes of Lucas Piazon, Islam Feruz and Wallace in recent years.
But it looks like they couldn't clinch a deal for Adrien.
