#3 A challenge for Juventus or a fantasy of football fans fulfilled
Cristiano Ronaldo has repeated a few times that he went to Italy seeking a new challenge, justifying his move to Juventus from Real Madrid. It is surely tough for a 33 year old to seek a new challenge, moving to a new club and settling in new surroundings with new teammates.
Despite the compelling nature of Serie A, Juventus were crowned the Italian champions 7 times before Cristiano Ronaldo's arrival. Serie A last had a different winner when it was won by AC Milan in 2010-11, and Juventus have won it for a record 7 times consecutively since then.
Lionel Messi's arrival in Italy for any club other than Juventus will make the title race more spicy and challenging for Juventus, but the long term fantasy of football fans around the world to see both Messi and Ronaldo in the same team will be fulfilled if Juventus get their hands on Messi.
