If Adebayor can score 30 goals in a season, then so can Bendtner. He scored 15 as a 3rd choice back in 2008 when he was a teenager. His first touch is sunday-league level at times, but his positioning and finishing is top class. He's definitely going to be a late bloomer like Drogba or Eduardo, but all he needs is consistency.
It's true that his horrible attitude and delusions of grandeur brings him a lot of criticism, but one thing that's holding him back are constant injuries. I don't think he has ever completed a full season without a massive injury that destroys his progress/confidence every single time. I wonder sometimes how the world would view him if he was a humble guy like Diaby.
Well, I think Adebayor is a better footballer but sure, he probably could score that amount of goals. As for his first touch, I'd put lots of emphasis on "at times" because he's actually quite technically gifted (for a big man ofc). But yep, you're right in saying that it's terrible sometimes.
It's also the fact that he never seems to be in great physical condition either. He's not fat or anything but he could definitely lose a pound or two.
If he can stay humble, stay fit, work hard and find some consistency he'll be a good striker.
his touch can be pretty impressive at times, watch this;
