Still very and unsportsmanlike that Mourniho decided to throw away his medal. Would he have picked it up afterwards? That lucky finder could become rich at an auction. But maybe that's typical for Mourinho, he just wants to win and is no longer satisfied with 2nd places. In competition it is a different story. He will be especially disappointed that he is not allowed to play CL with AS Roma now, because in the competition they have only qualified for the El or maybe even COnference kleague. A big difference.
I think Mourinho must have been very upset because of a match they should have won, but it had to be tarnished by the unfair actions of the referee in that match and I think it's only natural that Mourinho would vent his anger by throwing away his medals. Even after the end of the game Mourinho was still not happy with the loss which made him wait for the referee in the car park to protest in person. Apart from all that, Roma will still have the opportunity to start again from scratch in the European league next season and for sure Mourinho will try to bring Roma back to the final round.
