Have people actually forgotten the season before last, his first back here, when he had 12 assists in 30 games and about half a dozen goals?
Hardly the sort of figures of an impotent footballer some are trying to make him out to be.
His peak ability is very high so when he gets it right, he can be very good, even if it's just moments in games.
But obviously he's not producing them enough.
Plus he seems to have a pattern of managers picking him (I presume due to the ability) and then gradually not as the season goes on.
I'd like to seem him kept with us but as with all players at that age, he's unlikely to improve his consistency if he's only playing every now and again.
But I'd say his biggest problem, like Barkley in a way, is his unreliability.
Lukaku has similar faults to these two in terms of overall performance consistency but if you give him chances, he will score goals.
You can't say that about the other two, either for goals or for more equivalent situations in the game.
Managers like guarantees with players (that's why a lot of seemingly poor players, usually labelled as "favourites" get lots of games ahead of more talented ones) so I can see why Deulofeu slowly stops getting picked with each manager.
