Nah it is kinda correct to write in this way. No matter what his "broke out chapter" has finished. After this summer no matter where he plays he is considered a star and, even if he plays for us again, his role will no longer be the same. We must ask for more than what he did this season since he costs us 20m+ (if).
His next chapter is regular starter and a star in any top leagues. That's for certain. In a way this also means no chance he would stay in Chelsea unless he is guaranteed a starting spot.
