The midfielder's representative feels his client is quite an unique talent, and has revealed several European giants wanted to sign him last summer before he moved to ItalyPaul Pogba in the wake of the Frenchman's impressive performance in Juventus' 4-0 Serie A win over Udinese on Sunday.
The former Manchester United midfielder featured for the full 90 minutes and scored twice to help the Scudetto holders to three points.
"His valuation is not a problem. You can't put a price on him. Pogba is not for sale," Raiola told Corriere dello Sport.
"Paul is a bit like a Dali-painting. Pieces of art are very rare and are worth a lot because they are appreciated by a lot of people. Pogba is just like that.
"Juventus fans are concerned that they might lose him to some rich sheik-owned club? That's an understandable concern. I always look after the interests of my players.
"Clubs like Bayern Munich, Barcelona, Real Madrid and Inter all enquired about Paul last summer."
Pogba is under contract with Juventus until June 2016.
