Both teams are perfect match for each other because they are both equally strong. Juventus currently has the best performance after a long time, and this makes it difficult to predict the match. Inter have been very consistent in both local and international competitions, and I don't think that they will want to jeopardize with their reputation by allowing Juve to reap that off from them.
The match is very important for both teams to win, because the winner in this match might finally become the winner of Scudetto this season. However, the match is unpredictable and none of these two clubs should be underestimated.
It is still a long way to declare the winner in this match. perhaps the prestige of both teams will of course increase. fans of both teams will also be very hot. because only these two teams will compete for the trophy this season.
Inter's match against Fiorentina is also important for Inter to win. and then Inter can take better steps when facing Juventus. but the situation would be different if Inter couldn't beat Fiorentina. because that means competition will get tougher.
