Arturo Vidal has written a farewell message to Juventus supporters after he was unveiled as a Bayern Munich player on Tuesday.
The Chilean is reported to have cost Bayern £28m after another impressive season in Turin saw him lift the Serie A title for a fourth time and reach the Champions League final.
Vidal's last game for Juventus was the 3-1 defeat to Barcelona in the final last month, and he has shown his gratitude to the club's fans with an emotional statement.
"It's a very special day," the 28-year-old said in a message on Twitter. "I want to send a greeting from my heart to all Juventus fans in the world. Thanks for these four wonderful years together.
"I want to wish you all the luck in the world and I promise you that you'll forever be in my heart. In my soul, I will forever be a Juventus player."
Vidal won the Serie A title in each of his four seasons with Juventus.
