So what does Kone provide that Naismith doesn't, more tactical flexibility? I'm assuming you play lukaku up front by himself so your other strikers need to be able to do a similar job.
I really don't know. He's faster and stronger and when he initially played he was up front and took the pressure off Lukaku who was getting bullied by centre halves. I don't dislike Kone at all, he just lacks composure in front of goal and doesn't create a great deal.
