It's the sixth league title of Ronaldo's career.

The first came as a 22-year-old at United in 2006-07, ending a fouryear drought for Ferguson's squad as Ronaldo scored 17 goals - three fewer than Didier Drogba's leaguebest 20.

That was just a warmup for what came next.

In 2007-08, Ronaldo led the Premier League with 31 goals and helped United to the league title and the Champions League trophy, the club's third in total.

Another Premier League title came the following season as Ronaldo finished second in the scoring race with 18 goals, behind only Nicolas Anelka, who had 19 for Chelsea.

While Ronaldo won only two Spanish league championships in his nine seasons at Madrid, he also helped the team to four Champions League trophies - including three consecutive European titles over the last three seasons.

When Juventus acquired Ronaldo in a 100 million euro ($112 million) transfer last year, the expectation was that he would help end the club's long chase for a Champions League trophy.

Head coach Massimiliano Allegri insisted Ronaldo was the future of Juventus and the Portuguese superstar said he was "1,000 percent committed to staying" but the Turin giant needs to find more if it wants to conquer Europe next season.

This year, Ronaldo did his part by scoring a hat-trick to overturn a first-leg deficit against Atletico Madrid in the opening knockout round and goals in both legs of the quarterfinals against Ajax, but the Bianconeri were still eliminated by the Dutch club.

"Next year is a new page, the fans all want it and so do we," Ronaldo said.

"It is an important trophy, but it's difficult to win."

A Champions League title with Juventus would enable Ronaldo to match another multiple team record - Dutchman Clarence Seedorf is the only player to win the trophy with three different clubs (Ajax, Madrid and Milan).

Allegri, who has won 11 trophies since taking the Juventus job in the 2014-15 season, does not anticipate too much transfer activity this summer as he bids to mold his squad into a European champion.

"There's no point enacting a revolution," he said.

"We have to improve the quality of our football and learn how to deal with unexpected events better, because those moments can change a competition.

"I might try a few players in different roles.

"Paulo Dybala had a good season, especially up until January, because it was not easy to play along with Cristiano Ronaldo and Mario Mandzukic.

"Clearly, with Ronaldo by your side, you will play differently."
