It is tbf sometimes hard to avoid it, as the opposing view is often would you drop Palmer for Allen? Well, the answer from the manager is often yes! That doesn't btw mean that by definition Palmer is useless, or that there might not be times in the future when Allen is dropped for him in return!
Now, this ain't a Palmer thread and you're right, Palmer has very different strengths and weaknesses to Allen, but there does seem to be a serious blind spot wrt Allen just recently. We could list all our players' weaknesses, and there is merit in that from time to time(!) but at least be fair about it when doing it.
