Catch 22, that. Hard to start reading the game if you're not getting the minutes - at least he's getting in position to score, and he can finish.
I have to disagree, HB mate
He should know how to read the flow of play by the time he's 18. Given where he's come from (Chelsea), I'm convinced he was modeled and trained after the Drogba/Costa type, and so basically didn't have to think until the ball was in a crossing position, or else someone had a shot and he was near the rebound.
You're not wrong in that more minutes = more opportunities to learn, but it's a damning thing for English development that it doesn't train many players to be able to read the game properly and plan ahead in 2-3 moves. That's probably why English midfielders have a huge problem turning on the ball under pressure.
The fact that he can't read the game at 20 years old suggests to me that he'll be an ultimately fruitless purchase, in terms of being the starting striker here - unless something clicks with him very, very soon.
