Cristiano Ronaldo was officially unveiled as a Juventus player on Monday.The 33-year-old signed for the Old Lady last week in a deal worth a reported €100million to end nine glittering years at Real Madrid.Having won seven successive Scudettos, Max Allegri's side are in the hunt for the Champions League, a trophy which has eluded them since 1996.Their new addition has played no small part in that himself, scoring against the Italian champions in both the 2017 final and the 2018 semi-final.Now that he is to be found donning a Bianconeri shirt, few would want to bet against them going all the way next season."I do know that the Champions League is a trophy every club would like to win," he said upon his presentation, per the BBC."This is an option. We are going to fight not only for the Champions League but for the Serie A title."Juventus have long had a habit of buying up all the talent Serie A has to offer - notably signing Gonzalo Higuain from title rivals Napoli in 2016 - but their resources do not necessarily mean the race is over before it has begun this term.On the contrary, Jose Mourinho, who managed Ronaldo at the Bernabeu between 2010-2013, insists that Italian football has just got all the more interesting.

Ronaldo is a game-changer 

Speaking to Tele Radio Stereo, in an interview brought to our attention by 101GreatGoals, the Manchester United boss explained:

"The Spanish League no longer has the two best players in the world. Now one’s in Spain and the other’s in Italy.

"In England, the Premier League is the most competitive championship with top players. Now there are three dimensions to look at.

"Now everyone looks at Italy for Ronaldo, the Premier League because it’s the best league and Spain for Messi.

"Serie A has become one of the most important championships in the world. In football, everything can change."

Corruption and a perceived lack of competition has had a devastating impact on Serie A over the last decade, but Mourinho insists that it is up to Juventus' rivals to step up now that Ronaldo has arrived.

It will certainly be interesting to see how the resurgent Milan clubs, Rome's two representatives, and Napoli adapt to the challenge.

"If it changes the perspectives of teams like Inter, Milan and Roma, if they don’t passively accept Juve with Cristiano become stronger, that they will win again and again and can also find the right motivations from this deal, it can change Serie A in terms of quality, emotions and exposure," Mourinho added.

"For this reason, I congratulate to Juventus for this coup, which involves football, marketing and merchandising. It’s the complete transfer."

It's very rare you can say that about a player in his thirties who is costing a nine-figure sum, but the Ronaldo deal has to be the exception.
