Form is temporary, class is permanent. So was, for example, his terrorising of Liverpool in the EFL Cup last year simply a run of form. Is his current blip simply a loss of form (aka confidence?) or was he always over-rated? Time will tell, but for what it's worth I'm going with the idea we'll see him back to his best again soon. Whether he needs to be taken out of the heat of the kitchen is the one question that needs answering.
