Every summer, there are rumours that Depay may leave for a bigger and better project.
The recent transfer window brought rumours of a possible move to Liverpool, but nothing materialised.
However, Depay's biography Simon Zwartkuis believes the player is very happy in Lyon.
When asked by Tribalfootball how much Lyon and their fans mean to Depay, Zwartkuis said: "A lot.
"After his difficult time at United, he gave his career in Lyon a new boost. Before he came to France, Memphis asked a scientific data-company (SciSports) to analyse which European club would fit him best.
"Lyon was one of the five clubs that came out of this research. In Lyon he found back his joy in football and his joy in life.
"And again, he is not blaming United that he lost that in England, it was a matter of Memphis himself getting back on track."
Zwartkuis also suggests that Depay has an excellent relationship with Lyon president Jean-Michel Aulas.
He said about their relationship: "Good. Just look at the videos where Aulas gives post-match interviews and Memphis is walking by. They make fun together and respect each other.
"Aulas knows that Memphis is not the average guy and I think he likes that."
With that being said, Depay has a point to prove after his disastrous spell with United.
The PSV academy graduate was once tipped to become the world's next superstar.
While he is happy with Lyon, the Netherlands international does have one eye on the future and where he could develop his game further.
And Zwartkuis says the 25-year-old is ready for such a move.
Asked for his opinion about where Memphis may play in the future, Zwartkuis said the following:
"Memphis still enjoys playing for Lyon and they will be in the Champions League again, so I don't think there is a urgent reason to leave.
"But he has never made a secret of the fact that he wants to end up at a club on the absolute top level of Europe.
"I think he is ready for that, when you look at the level he reaches in the national team, also in the big games against France and Germany.
"I would like to see him one day at a top club in Spain or going for a second chance in England."
