We've a recent history of playing without an out and out striker but I don't think it's too much of a problem when you have midfielders that can score. Forrest, Christie, McGinn, Armstrong can all find the net.
Dykes can chase lost causes and hold it up. Naismith gets criticised but the last games he played I thought he was terrific. He takes the pressure off the defence and pushes us up the pitch. If Dykes can do that I will be very happy.
