Cristiano Ronaldo ready to seize Juventus 'challenge' after move from Real Madrid

The 33-year-old was unveiled by the Serie A champions on Monday after passing his medical

Cristiano Ronaldo says he remains as ambitious as ever as he was officially unveiled as a Juventus player after completing his £99.2million transfer from Real Madrid.

The 33-year-old Ballon d'Or holder was unveiled by the Serie A champions on Monday evening after passing a medical earlier in the day.

The blockbuster move came as something of a surprise but the Portuguese insists he is just as motivated as ever to prove himself in Italy after record-breaking spells in both England and Spain.

"The nine years at Real Madrid were wonderful, but it's a brand new step in my life, so I thank all the supporters with my heart," he told a press conference in Turin. "But I have to focus on this next step. I'm looking forward to playing. I'm very motivated, concentrated and focused on that.

"I'm going to try to show that I am a top player, as usual. I'm going to work hard in training. I don't think I have to show what I am more than that - you know my stats. But I am very ambitious and I like challenges. I don't like to stay in my comfort zone, I like to seize new challenges.

"After the experiences in Manchester and in Madrid, I'd like to mark the history of Juventus. I like challenges, again, and I hope everything will go very well."

Ronaldo revealed he had chosen to join Juve rather than head for one last big pay day in the Middle or Far East.

He added: "I'm here because it's a brand new challenge for my career. It's a big club and usually players of my age go to Qatar or to China, with all due respect, so coming to such an important and outstanding club at this point in my career makes me very happy.

"That's why I'm very grateful to Juventus for this opportunity because I can go on with my career."

Asked what Juventus could give him during his four years in Turin, Ronaldo replied: "I can see that Juventus is a club that can have many successes.

"They have won domestic cups and Serie A titles, and they were in the final of the Champions League, so I am so proud to be here, I am so proud that they were interested in me.

"I hope I can give the best response on the field during matches, that's what I can do. I hope I can take them to an even higher level."
