"A player unlike any other, versatile and capable of occupying literally any position on the pitch – as demonstrated in recent months in which, starting as a midfielder, he has been able to express himself at a high level as a scorer, finisher, winger, full-back and even defender," Juventus said in a statement.
"A powerful tool that can be used on both the right and left flanks, available to Coach Spalletti to attack any opponent. A young man who has won the hearts of the fans and is now reaping the rewards of his daily work in training.
"Congratulations, Wes, from the entire Juventus family!"
