Does his role not factor in at all?
14 starts at CF, 4 starts on the wing, 14 sub appearances (and who knows how many of these had him out wide).
Of course a young player isn't going to perform when he's getting jerked around all the time. That's a big part of my point.
Yeah, it does when you're talking about his goal return. It might not be ideal, but plenty of players get shunted in positions that aren't always their favourites (see Sigurdsson too a lot of last year, Rooney at Man Utd went all over the place, etc etc).
I'd still say though he has had in that time plenty of chances to be involved, to get into scoring positions, to know what it's like to play games at this level of his age, plus he did get a good number of games centrally last year too. I'd say 14 as CF gives him very decent exposure of it.
You also have to be somewhat flexible though at that age getting into a PL team.
However, yes I think that equals regular game time for someone of his level of development.
