Cristiano Ronaldo gave Juventus a second reason to celebrate its Serie A title triumph as he confirmed he is "1,000 per cent" staying at the club.

Juve beat Fiorentina 2-1 at home on Saturday to sew up an eighth successive Scudetto and first for their superstar forward.

The extension of domestic dominance goes some way to justifying the Bianconeri's massive €112million outlay for the now 34-year-old, who joined from Real Madrid 

Some discussion over whether that investment was worthwhile emerged after the club's Champions League exit at the hands of Ajax and subsequent reports indicated its talismanic attacker could look for a new challenge after just a single season in Turin.

But, after becoming the first player to win each of Serie A, La Liga and the Premier League, Ronaldo dismissed all doubt about his future. "I'm very happy," Ronaldo told DAZN .

"First of all for winning the Scudetto and then for being the first player to win the Premier League, La Liga and Serie A.

"We were not able to win the Champions League, but we will do better next year," he said.

Asked directly if he will be at the club next season, Ronaldo responded: "1,000 per cent."

The Portuguese played a significant role in leading the Bianconeri to an insurmountable lead with five games to spare, netting 19 goals in his 27 league appearances.
