The 36-year-old Ronaldo has a year left on his contract that pays him a massive €31m net per season.
He said: “I have to value everything we achieved this season at Juventus, both in collective and individual terms.”
During his three years in Italy, Ronaldo has also been named Serie A footballer of the year twice, and was the competition’s top scorer in the season just completed.
In an Instagram post, he added:
“The Italian Super Cup, the Italian Cup and the Serie A Top Scorer trophy fill me with happiness, mainly due to the difficulty they carry with them, in a country where nothing is easy to win.
“With these achievements, I reached a goal that I had set myself since the first day I arrived in Italy: to win the Championship, the Cup and the Super Cup, and also to be Best Player and Top Scorer in this great football country.”
The former Manchester United and Real Madrid forward has won major individual and team honours with clubs in three countries.
“Nothing compares to the feeling of knowing that I’ve left my mark in the countries where I’ve played,” he added.
This season he scored his 100th goal for Juventus, having also passed the milestone at Real Madrid, where he scored 450 times, and United ,where he got 118 goals.
He also passed 760 career goals, giving him a disputed claim to being the highest scorer of all time.
Juve are in rebuild mode, with an aging squad that is overweighted with older stars on too large contracts.
Ronaldo leaving will free up a lot of money for Juventus to reinvest in the squad this season, and will provide a path to the first team for some of Juve’s young talent.
The big question is where does Ronaldo go? He has played in the Premier League, La Liga and Serie A. Does he return to Portugal and Sporting or does he move to PSG and add a Ligue 1 title to his collection?
With the World Cup in a year, I cannot see Ronaldo returning to Portugal just yet. I expect him to make a move to a club in one of the big five leagues?
