No need to feel bad. He has been fortunate to get a Juventus salary for many years despite being pretty useless. It is quite telling that often when we finally manage to let go of players, then they cant even get playing time at clubs playing 4 levels below.
his wages will probably be paid, and in this situation, we can't really expect much more. he only played 13 matches in 2020, only 2 in rennes, and he's coming back from a lenghty thigh injury. he's broken goods at the moment. toro is the ideal club for him: they're shit, rugani helping them to some points would be a massive success already.
