"He's an extraordinary footballer, on both a technical and professional level," Raiola told Radio Anch'io Sport.
"He grew up in Armenia, then moved to Shakhtar Donetsk. He can create assists and goals, he's useful to a team.
"He's suitable for Juve, he can be part of one of the top 10 teams in the world. However, it's difficult to see Borussia Dortmund letting him go, but he could bring something extra to the Italian League.
"We'll see if he can get to Serie A."
