Juventus became only the second team to win Serie A without losing a game after Fabio Capello's AC Milan in 1991-92 and the first to achieve the feat in a 38-match season.
Del Piero spent 19 seasons with Juventus. Here is what he wrote to the supporters:
NOTHING CAN BE BETTER THAN...
Than eight Scudetti.
Than a promotion from Serie B.
Than a Coppa Italia (let's hope two).
Than four Italian Super Cups.
Than a Champions League.
Than a European Super Cup.
Than an Intercontinental Cup.
Than a goal scored against Fiorentina.
Than a Del Piero style goal.
Than a goal in Tokyo.
Than my tears.
Than a goal in Bari.
Than a back-heel volley goal in the derby.
Than a goal for the Avvocato.
Than a tongue stuck out in a game against Inter.
Than an assist to David.
Than goal number 187.
Than a goal in Germany.
Than a goal scored against Frosinone.
Than a top goalscorer title in Serie B.
Than a top goalscorer title in Serie A.
Than a standing ovation at the Bernabeu.
Than 704 matches in the black and white jersey.
Than 289 goals.
Than a free-kick scored that meant the Scudetto.
Than a goal against Atalanta.
Than any record.
Than the No 10 jersey with the name Del Piero.
Than the captain's armband.
Nothing, but...what you have given me in these 19 years.
I'm happy that you have smiled, cheered, cried, sung, shouted for me and with me.
No colour will ever be brighter for me than black and white.
You've made my dream come true. More than any other thing, today I just want to say THANK YOU.
Always by your side
