Palermo striker Paolo Dybala has officially joined Juventus on a five-year deal worth 32m euros, the Turin giants announced on Thursday.

Argentinian Dybala has been one of Serie A's sensations, scoring 13 goals in 34 appearances and showing his play-making skills by assisting plenty of others as the Sicilian club closed the season in 11th place last week.

Juventus, who will face Barcelona in the Champions League final on Saturday in Berlin, said in a statement: "Juventus Football Club can announce that an agreement has been reached with Palermo for the services of Paulo Dybala, who has signed a five-year contract.

"A fee of 32m euros, payable over four years, has been agreed, with a potential extra 8m (euros) to be added on if certain performance-related targets are met."

Juventus clinched their fourth consecutive title this season and their first Cup double in 20 years.
