I got Grenier for 19 million in my Athletico Madrid save (pretty expensive) and his value was only 9.75 million in first season. However, he got 21 assists and 9 goals in the first season. Second season, he got 36 assists and 12 goals. In the third season, he developed into a world class advanced playmaker and his value increased to 43 million, he got 48 assists in 50 games and 16 goals. A good buy if you ask me and he's still young.
