You're wrong, no?
He is 18 and it's hard to tell at this point how his body will develop and what opportunities will arise. He looks more effective coming from the back when our forwards distract defenders and he is already at his full speed when defenders spot his run. When he plays wide forward his initial speed is not enough to give him that advantage, but with time he could develop better dribbling skills to go past defenders more effectively.Don't see Saka as a wide forward. As an orthodox left winger or left back, I think he'd be electric. He's got great close control and can drive from deep.
I really like the idea of Fraser coming in as Saka, Nelson can play as orthodox wingers. Whereas, Martinelli and Pepe seem to be genuine wide forwards.
I'd love to go two up top for some home games with two wingers.
The only important thing for him now is that he plays and doesn't get dropped because he is 18-19, like what happened to Martinelli.
