They also have to prepare for the Champions League final. In France, Paris Saint-Germain's job is easier, they have already declared their championship. That's why they can easily put their reserve players on the field in League matches. That's why the French team's players are luckier in terms of rest.
Chance of playing a Champions League final match is so rare and there are very limited clubs won Champions League so far. Inter Milan with their past titles there know that it's never easy to win this biggest trophy in Europe. With a final match ahead, Inter Milan knows that they are counting down day by day to play it, win it and make history for their club.
There are only three Italian clubs won Champions League so far with their titles as follow: AC Milan (7), Inter Milan (3) and Juventus (2). Inter Milan would like to win another title and and enrich their club trophy history as above them, there are some clubs including Real Madrid (15), AC Milan (7), Bayern Munich and Liverpool (6), Barcelona (5) and Ajax Amsterdam (4).
Inter are still competing with Napoli in the hunt for the Scudetto, but PSG have already secured the Ligue 1 Trophy. This condition makes Inter players have to use all their abilities to win the title race, the risk of injury is very vulnerable at times like this and if that happens it will be very detrimental to them in the UCL final.
It is still difficult to predict who will win the UCL trophy this season because both teams have the same squad quality, but if Inter loses important players due to injury, then PSG has a great chance to win the Treble Winner.
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.
