Inter have lost many titles this season that they should have won, the Coppa Italia, the Italian Super Cup and the Scudetto, so it is clear that in this final they will try to win it, as explained they have what it takes but still this is the UCL final and it must be remembered that PSG also wants this title. Under Enrique PSG appear with a different style than before, the cooperation between the players is very good and this is the real power of football. Let's enjoy this final which is only a few days away.
It will surely be season to forget for Inter Milan if they eventually lose out on the trophy to PSG, just as you said, they've lost trophies this season that were supposed to be at their disposal. The last resort for Inter Milan is this trophy and we're also aware that they started dropping points unnecessarily in the league when they got to the Quarter finals of the competition and it continued even after they eliminated Bayern Munich to face Barcelona. In fact before the first leg game against Barcelona, they lost three consecutive times, twice in the league and once in the Coppa Italia. So if they lose this, it's definitely going to be a big blow to them.
