The coach must analyze the defeat to evaluate and identify tactical or strategic errors used. Juventus squad still has some weaknesses and it is natural that they lose to Manchester City, the coach must see this as a threat to his team when the season officially starts, he must immediately make plans to improve the team's performance.
Management still has time to bring in several players who can improve the quality of the team so that they can achieve the set targets. Juventus once dominated Serie A for several seasons in a row, it would not be difficult for them to become the new champions in the domestic competition if the coach is able to develop strategies and improve the quality of the team and anticipate any weaknesses.
Juventus have not been able to rise for several seasons and even Juventus last won Serie A 5 seasons ago so this will not be easy for Juventus after experiencing many changes.
What happened in the Club World Cup should be able to be an improvement for them to face next season and we have not seen the big steps they have taken but I am still quite optimistic if Igor Tudor continues to be trusted to be Juventus coach and is supported to bring in quality players then there is a big possibility that Juventus can compete fiercely for the Scudetto next season.
