Juventus are not playing in many competitions this season so it is advantageous for them to focus on Serie A and can also avoid player fatigue and injuries. The match between Juventus vs Inter Milan ended in a draw where both teams were only able to score one goal each in the match. The competition between Inter Milan and Juventus will be even more exciting because the points between the two are quite close, which will give rise to a much more competitive rivalry.
Almost all teams will have difficulty focusing in many competitions because it can make players tired and injured, especially if the squad they have is not comparable so it is difficult to rotate. But Inter Milan can definitely overcome that even though in the end they failed to win many titles in one season.
I don't think it will have a big impact on the team, in fact teams that play in several competitions, especially those that play in European competitions, will have greater motivation and will also be able to build a more solid chemistry within a team to show or maintain their consistency.
However, for Juventus, who do not have a qualified squad this season, between the core players and the back-up players, they have a slight advantage because they only need to focus on their Serie A matches.
And it must be admitted that Juventus' performance this season has improved quite significantly when compared to last season so that now they can compete at the top of the standings for the Scudetto.
