tbh, i have always seen Lukaku as more of a counter attacking striker cos he needs acres of space of space due to his poor technique. This is where he is his most effective with his power and pace breaking free. He is also quite good shooter from the mid-distance. Still, Lukaku had time enought to develop a more complete skillset and he always knew that ppl wanted him to be more of a target man simply bc that is what you need from your big striker esp when playing against buses. here in the PL his counter attackign ability means jack shit in most games. Very few games, like the one vs Southampton are made for a counter attacking striker and he shat the bed there, so not exactly making a strong point here.
TT will be aware of how Lukaku thinks and consider it in his decisions.
