Well, good to see Livaja scoring some goals and he has potential to be quite a versatile attacking player. Hopefully he'll remain starter in Europa League and if he continues to do well, then get more minutes in Serie A too.
Tho indeed, getting rid of Castaignos I still believe to be a massive mistake and even if we wanted him to remain initially, we probably didn't do much to convince him to change his mind and at least accept a loan. I am reasonably certain that barring any serious injuries, this kid will eventually become one of the best goalscorers in the world. His natural physical build is fabulous for a central striker (a great balance between strenght, height and speed), technical ability is quite good and elsewhere in his games, he hasn't got any problem he cannot overcome with experience. I think the mistake we might've made was that we thought (at least I at the start did think so) he could be some kind of a Cristiano Ronaldo type player who can score a lot while being a support/wide player. I'm quite certain that had he played in Siena instead of Destro, he would've scored more goals than Destro did.
