Give Kane no support. No midfield. Aerial hoofs into the channel to run over to retrieve 45 yards from goal. Would he score 30 in a season?
I'm not comparing DCL to Harry Kane, I'm merely suggesting you look beyond purely the goal tally and look at his overall contribution. It's hard for a 20 year old striker in this league. Even more so when he spends the game in another postcode to an insipid midfield who soil themselves when faced with a forward pass.
He's improved massively from last season. Give him time and he will be good. Not top class but far from terrible.
He's a 20-year-old kid playing in the Prem, thrown in at the deep end and is still only really beginning his career.
To write him off now is just being dead weird. In comparison, Kane had gone through 4 loans and had made more than (I can't be arsed doing the maths) 50 appearances - DCL's made barely just half of that this season alone.
