But indeed at this time with a score of 2-0 it was also very enough to bring them to the most comfortable position at the top of the standings with a difference of 2 points from Juventus as the closest competitor.
It is surely enough, even 1 goal is enough. The most important thing that Inter Milan could get 3 points in the match. They need full points to keep their position in the top standings of Serie A. They must be very careful because Juventus is in 2nd place and only have 2 points difference.
The previous few seasons Inter have always been like this even last season they were 7 points clear at the top but this sudden drop in performance always makes the situation worsen by itself for Inter so to minimise things like this from happening this season then Inzaghi must be more focused and more serious in organising rotations for Inter so that they are not only focused on one competition and must be more able to do consistency in every match that is run.
Inter Milan must be aware about the potential drop in their performance. They need to keep their motivation in competing the title. The bigger challenges will happen in the second half, sometimes many teams drop their performance when it is toward the second half. You're right that one of the solution is about rotating the players on the starting lineup. Inzaghi needs to try this way, it also minimizes the chance for injuries, too.
