I don't think we should overdo it. Igor Tudor hasn't proven anything yet, and Juventus, who have been working hard to develop their team every season, haven't seen any evidence of that, especially since their rivals in Serie A are also developing much stronger teams. So, I don't think Juventus has a high chance of competing or winning the Serie A title next season.
If Juventus keeps the players they used for the Club World Cup, I believe they will have a good chance of winning the Seria A. If the manager has enough experience, it doesn't matter how many seasons he has been at the club, the players have pre-season games to get to know the manager and what method he plans to use. Igor Tudor has yet to show anything at Juventus, although they had a fantastic game in the FIFA Club World Cup, even Real Madrid, which eliminated them, only scored one goal.
Igor Tudor must strengthen his attacking lines, they miss opportunities while playing against strong clubs, they can score against weak teams, but they wasted several chances against Real Madrid. I believe that some people will continue to underestimate Igor Tudor because of his old club Lazio, and when he took over Juventus, they struggled to make it among the top clubs for Champions League spots.
