With the international break I'd expect either Lukaku or Kone (if not both) will be fit for the next game, therefore it shouldn't be an issue.
If this isn't the case then I'd opt for probably Naismith as he's the more natural forward / finisher. Barkley as a forward is a definite no-go.
Also I doubt Mirallas would thrive as the lone man, as it would require too much effort and concentration for him to muster.
It's often a selfless role to lead the line and I doubt it's in his nature, as he is only really truly happy when the ball is at his own feet.
Young lads option is also a no-go from me, or at least under the current circumstances. Lots of pressure and doubt the atmosphere is right.
