What role do you use for him(Lukaku)? For me he is AF, but scoring few goals, nothing special, i'm in december, first season. Most of the goals are from my IF Depay and Winger Sisto...Depay is a scoring machine...
As for your question - Tielemans, Florenzi(CM -A), Roberto, Saul, Ginkel, Kovacic, Roberto Pereyra(class).
