For some, it still seems strange that Cristiano Ronaldo is a Juventus player.
Ronaldo had plied his trade at Real Madrid for no less than nine years, becoming an icon in the famous white jersey and perhaps securing the status of the club's greatest ever player.
That's no small statement when the likes of Alfredo di Stefano, Ferenc Puskas, Zinedine Zidane and Ronaldo Nazario have all turned out for Los Blancos.
His time in the Spanish capital came to an end this summer, though, with Ronaldo seeking a new adventure in Italy with its leading club.
Ronaldo's agent has even confirmed that Juventus will be his last club in the game and the Portuguese has his heart set on Champions League glory.
How is Ronaldo settling in?
Juventus fell at the very last hurdle in both 2015 and 2017, so many believe that Ronaldo could be the difference between another close call and going all the way.
On paper, that seems pretty easy because, well, Ronaldo just happens to be one of the greatest players of all time.
However, even for a player like Ronaldo, settling into a new club and league is no easy task and that's not mention the fact he's now comfortably in his thirties.
Journalist provides insight on Ronaldo
That considered, just how is the 33-year-old settling in at Juventus?
The Daily Mail spoke to Italian reporter Gianni Balzarini - who is close to Juventus - about that very question and he had some rather interesting insight to give.
"When the Juve players arrive at training, they find that Cristiano has already been there for a while. And he is always the last to leave. The rest of the group were amazed by his approach," Balzarini noted.
"Juventus players are told that every season they start from zero. What happened before doesn't matter, they have to be hungry and motivated. That sits perfectly with Ronaldo.
"He is the embodiment of that determination to improve every day. Ronaldo and Juventus are the perfect match.
Ronaldo's house is now prepared
"'Ronaldo already knew the old guard of Andrea Barzagli and Giorgio Chiellini. He is settling in well.
"He knew a bit of Italian and it won't take him long to add more, speaking Portuguese and Spanish will help him learn quickly."
Different club, different league, same Ronaldo.
It seems Ronaldo is going all out to ensure his Italian adventure is as successful as possible, maintaining his furious work-rate and even ensuring his new house is up to scratch.
The Portuguese has both an indoor and outdoor swimming pool to help him with recovery and has his very own staff - from nutritionists to physiotherapists - living in lodges at his property.
So, if Ronaldo isn't successful in Serie A, it certainly won't be for a lack of trying.
Football fans will keep a keen eye on his progress in new surroundings and wonder whether they can continue to maintain his incredibly high standards.
Winning a league title, Champions League crown and Ballon d'Or in a third different league would give him a powerful argument in the GOAT debate.
