Today is a special day for @juventusfc! 💪🏽 #FinoAllaFine #ForzaJuve #SK6 @cristiano pic.twitter.com/iU4ULPeHmg— Sami Khedira (@SamiKhedira) July 10, 2018Ronaldo began his career at Portuguese club Sporting before joining United in 2003 and it was at Old Trafford where he set about becoming the superstar he is today.“He didn’t arrive at Manchester United as someone who was setting the tone for everybody else,” Gary Neville told talkSPORT in 2016. “It wasn’t a case of he came in and all of a sudden everyone else upped their game, that’s not how it was.“He became that out of what was in that dressing room. Cristiano was butchered and battered for two or three years at Manchester United and he has said it made him a man.“He was setting the standards when he left, and he became someone who would come in and do half an hour before training and an hour after training, but there had been 20 players per season for 15 years doing that every day. “The club, and Sir Alex [Ferguson], and the players all set the tone for each other. If you look at his performances in the first two or three years, his maturity, his decision making, his physicality, his petulance, they were all smoothed out over a period of three or four years at the club.”In a trophy laden career so far, which has also brought an incredible five Ballon d’Or awards, Ronaldo has scored 658 goals for club and country and is second on the all time list of international goal scorers with 85 for Portugal.Juventus have won Serie A for the last seven seasons and were beaten 4-1 by a Real Madrid team containing Ronaldo in the 2017 Champions League final. The Italian side are now set to beat their own transfer record, set in 2016, when they paid Napoli £75m for Gonzalo Higuain.
