Shitting myself about our LB situation, our LBs are all injured except Vertonghen but we need him in the middle against Lukaku. Chiriches had started really well but Lukaku is too dangerous for him to handle.
Rather than worry about Lukaku Vs your LB, I have to point you to Coleman who always plays like a superman against you lot for some reason (I don' know if you remember, but that debut he had against you 3 years ago left you destroyed at that side)
A lot of people seem to ignore the fact that Lukaku have brought us another hidden positivity which is give the other players a remarkable space and time due to his movement and his inducement of fear to defenders.
I think the focus should be controlling the the wings rather than worry about Lukaku.
