Carlos Tevez's hunger to accept the challenge offered by Juventus convinced him his time with Manchester City was finally over.
The 29-year-old Argentinian was unveiled in Turin on Thursday morning after signing a three-year contract with the Serie A champions, bringing a four-year spell with City and seven successful years in the Barclays Premier League to an end.
"I spoke to Manuel Pellegrini as soon as he arrived at City," he told juventus.com. "I told him I considered my time at the club to be over. He said that was fine by him and there weren't any problems in allowing me to leave. I would like to thank City and all their fans for the four years spent together."
Tevez first arrived in England with West Ham before winning the Champions League with Manchester United in 2008, and after switching allegiances in the north west, he won the title with City last year.
That he played a role in that campaign at all came as some surprise, however, given the six-month exile that had followed his refusal to warm up in a Champions League game against Bayern Munich in September 2011. A January move to AC Milan then failed to materialise.
The row cast a shadow over his final season and on Thursday Tevez confessed he had decided to follow sacked manager Roberto Mancini - his nemesis in Munich - out of Manchester in search of a fresh challenge.
He added: "Four years ago, I chose to move to City because of the targets they were aiming for. I wanted to play in the Champions League and help the team win a league title after a long gap.
"I've noted the same ambitions at Juventus. They want to keep finishing first in Italy, as they've done over the past two years, and aspire to win the Champions League. This made my decision easier.
"Juventus have shown themselves to be a great team. The side features great champions such as (Gianluigi) Buffon and (Andrea) Pirlo, with whom I'm sure it will be very easy to play alongside.
"What interests me the most, however, is the team itself. That's why I'm not thinking about topping the goalscoring charts. If the team play well and win, it will be easier for me to achieve personal goals."
