I know what you are getting at but i too would prefer he scored 30 goals than 15.
I think we all would, but the general point is about how everything nowadays seems to to be judged on absolute measures rather than relative ones. Everything from goal output, transfer spend, minutes played, etc. Football has become so binary that sometimes a lot of context is missed in the analysis.
Nunez has suffered from many different things during his start - not least of which was joining an exhausted squad that had massive expectations on them after last season. Plus we've had injuries to key players, a new system bedding in, a disjointed midfield, Mo often out on the touchline (instead of linking up with him), plus Halaand's scored a truckload which has drawn unfair comparisons - the list is endless of how he's been judged (often unfairly) in his brief time here. All those factors don't even include a new country, new home, new teammates, new manager, new tactics, and a new league. If he scores 10-15 in his first season then so be it. He might well score 25 a season after that.
Of course the sending off didn't help, but all things considered, there was more of a chance he'd have a slow start than hit the ground running (given the wider issues in the squad), which makes the early judgements of him so difficult to understand. He’s played just 176 minutes of premier league football yet is already being questioned by some (and almost written off by others).
He has all the ingredients to be a monster player - power, strength, pace, good in the air, finds space, creates chances for himself, and is getting into the right positions. Once everything clicks with his teammates, and once he's up to speed with our system and we have key players back fit, I'm sure Jurgen will turn him into an elite premier league striker.
