I think this deal is a very good one for Fiorentina, because his transfer value is at the moment on the maximum. Cuadrado is 26 years old and has at the moment the perfect age for playing football, but in two or three years his value should be about ten millions. I am not sure how profitable this transfer for Chelsea is. FC Chelsea has enough good and young players in the midfield where they are planning to station Cuadrado.
Fiorentina can buy two very good and younger players for that money. I have no current information about the plans of Fiorentina, what they are planning to do and how they want to invest the money. For me there is only one sure thing, Fiorentina made the better deal.
