There isn't the smallest chance for Roma to win the Scudetto, Whoever believes that must be delusional. I was solely talking about Lukaku and his performance at the moment and I think that the 4 goals in the European Championship qualifiers have done him well. It gives him confidence and that can only contribute to his performances in the club. He has Mourinho's trust and if he stays in shape for a long time, his contribution to whatever goal Roma will achieve in the end will certainly be of significance.
You mean Lukaku can scored 4 goals in the international break, when Belgium plays against Azerbaijan? Actually, Azerbaijan doesn't have many good players, so it's reasonable that Lukaku was able to scored 4 goals in that match. But yes, it was also a good performance from him. And Lukaku should be able to scored more of goals at the Roma club later, because his confidence will increase when he returns to the club.
