Lazio coach Maurizio Sarri regrets leaving Chelsea for Juventus.
Sarri won the Europa League with Chelsea in his one season in charge.
He recalled to La Repubblica: Everything was owed to Juve and we just had to win the Champions League, but it was a contaminated message.
"I won the championship with a group at the end of the cycle and a club that took me on because they had the desire but not the conviction to change their style.
"At Chelsea I found it difficult to immerse myself in an atypical club, without a sporting director, where no coach could last two years.
"But then in the last few months I've had fun and I was wrong in wanting to leave, not so much from Chelsea, which would have also kept me, but from the Premier League, a context of unique beauty.
"Returning to Italy was a mistake."
