I know Youtube isn't a reliable measure, but he genuinely looks very good for his age. And I know people like to criticise the standard of opposition, but he's doing things with the ball that ordinary players can't just do. For comparison, I watched Ivan Toney's 37 goals and assists in Brentford's promotion season, and while he's clearly an effective striker with decent movement and anticipation, he's not doing anything special. Which translates into 6 goals so far in the Premier League. Meanwhile Alvarez is doing things with the ball that wouldn't look out of place in our team. The question is whether he'd be an Aguero or a Jesus.
