PSG has far more options now to control for muscular exhaustion. Just look what they did against Montpellier and at the same time Inter Milan has to be careful with players like Martinez. He has been out because of muscular fatigue for over a month in total now and they are trying to give the time he needs to be recovered as much as possible until that final takes place while not risking to give up on the Scudetto.
PSG has a few players who have been prone to muscular exhaustion in the past and the most important of them is Dembele and they will be giving him breaks. For both clubs the CL is probably highest priority, but Inter Milan has to try everything to win that Scudetto.
Inter Milan will do anything possible to win the Champions League this season, but PSG will not be as easy as they think, so they will have to be extremely careful in the final, as PSG moves are always unnoticed unless after their move. So the final will not be as easy as we expected, and PSG injuries will not affect them because there is more than two weeks from now, and they will make any strategy possible to win this trophy, as this is one of their struggles since the creation of the team, so it will not be as easy as we all expect it to be for Inter Milan.
If you reconsider the bracket and what teams made it to the final round, I think not a lot of people would have bet their money on the final being Inter Milan vs. PSG. In some way both teams have surprised many of us and more than fulfilled any expectations.
I thought PSG would be out against Liverpool and that was at a time when Liverpool was actually playing the perfect season. I couldn't imagine they kick them out.
Inter Milan had to beat Bayern and Barcelona and that again was not what most people thought would happen. But it became clear that Inter can't be underestimated because they have a specific quality that hurts all the top teams.
That is why this final will be interesting and for PSG specifically, it is all about breaking the curse and finally win that trophy they have been after for such a long time.
