This could be the very reason why they lost as well. People think that Juventus suddenly became bad when they were at the top of the list and yet they do not see why. It is obvious why, because we are talking about a team that is filled with old players, which makes it very hard for them to have a win when all these players start to grow tired.
They start the season great, but gradually become more and more tired, and that shows in the results as well. They need a younger setup, at least younger bench, so that they could end up with some subs during the games that could help them. If they keep this old age situation going, then I am pretty sure that we are going to see them not do all that well, they will be pretty bad.
I also think that there is a need for rejuvenation in the team. It is a team with a high average age and Juventus will need to reduce this average. If they do not lower the average age, this will be a problem that will make itself felt in the middle of the league. They will also compete in the UCL next year and will have tiring matches. That's why they will have more intensive work than usual staff intensity. Even though they did not play in Europe last year, we saw a performance from them falling behind in the second half of the league. It may be different this year, but they should include young players in the team.
Juventus is having difficulty building squad depth, as they are currently experiencing a financial crisis. Things got worse when they were banned from playing in European competitions, and Juventus also failed to win the Scudetto last season. Their income has clearly decreased due to failure to achieve success, and perhaps they will sell their star player Vlahovic to balance the club financial situation.
Meanwhile, perhaps the best way is to maximize the potential of young players, and release most of the veteran players in the squad, so that Juventus can slowly get out of its various problems. Next season Juventus will return to the Champions League, Thiago Motta will have a tough task to balance Juventus performance in domestic and European competitions.
I think that with Juventus condition, their movement in the transfer window will also be limited, but in that case several other Serie A teams are also experiencing a financial crisis. Motta certainly needs time to adapt, Juventus management should give him time to process, especially if Motta has to rely on young players next season.
