We'll see if Juventus will be able to compete next season by looking at the existing line-up and whether Thiago Motta can take advantage of the players in his current squad, and some of the new players Juventus have bought will have a positive impact on the club, I think if Motta is consistent and can bring out the performance of existing players next season Juve can compete for 4th place in the standings, but for the competition to top the standings I think it will take time for Juve and Thiago Motta,
Last season, Juventus started the season very well, although they were not consistent enough until the end of the season and if the target is only to be in the top four of the standings, I don't think it will be difficult enough for Juventus next season. However, the target of a team as big as Juventus is certainly not that, but rather competition at the top of the standings because in the last two seasons Juventus has not been in a bad position in the standings. So there is a good chance that Juventus can experience quite significant changes when they are handled by Thiago Motta.
Yes last season consistency was their main problem so they couldn't keep providing tight competition and in the end let Inter Milan go further to leave them behind. This is a fundamental problem for several teams where at the start of the season they can perform well but as time goes by they experience a decline and this has an impact on their game and also their position in the standings.
It won't be easy for Juventus, because next season they will start with a new coach. New coaches need time to get to know their players very well, so that may be an obstacle for them. But I still hope they can do it quickly, so they can show a promising game even when they first join.
Serie A has become increasingly competitive lately, so we might see even more competitive competition than usual. Of course I hope for that, because I can see that the league is even more interesting with tight competition.
