Inter Milan knows that with only one point less than Napoli, they can win Scudetto at the final day and in history, there are many examples that Scudetto only was known at very last minutes in the final match day of Serie A. The same examples can be found at other top leagues in Europe as well so Inter Milan have no reasons to give up when the league has only two matches for each club.
Inter Milan surely consider Champions League title is more valuable than Scudetto but they will not use it as a reason to give up in Serie A. They will try to win all two remaining matches and see how Napoli perform, then destiny will decide the winner of Serie A in this season.
It doesn't make much sense in my opinion to think about Serie A when you're one step away from the Champions League Cup.
The only thing Inter can do is win and hope that Napoli makes a misstep. And mentally focus on the Champions League.
There is no comparison with the goals.
