In my head i'm framing him as French DCL but with a better ceiling just to manage expectations for now.
I think he's probably quicker across the grass, but not as good holding the ball up (yet). Seems to have a similar good aerial ability.
I think if he reaches double figure across the season (all competitions) it'll be a success. I expect he'll blow hot and cold where Beto will take the load (I expect him to also reach double figures).
The key this summer is supplementing N'Diaye with a few more wingers that can push double figures in goals.
We need to take the load of this lad and just let him develop.
There is the outside chance though he could just hit the ground running and fly, think that would be an unreasonable expectation though.
