Issue with that is that he doesn't look like he can at the moment.
His running with the ball seems much more laboured than last season; or at least in the 2 spells (early on and post injury) when he was fresh.
Compare his runs against Arsenal.
For his goal last season, he powered forward, leaving players in his wake and skipping past the defender in the box.
For his assist to Naismith this season, he gets past the initial man, however his control was laboured and by the end he had to pass it as he was getting caught up by the defenders coming back to him.
No idea why this is the case, obviously.
I just don't buy into the lazy argument as he clearly spends a lot of time learning about football etc.
There is also the argument that big strikers don't have the same mobility/stamina as someone like Naismith who are simply built differently. They're built for powerful bursts not constant legging it round the pitch (this is from Zlatan's book...
But as I said, he can/should be more dynamic than he is at the moment. And whoever it's up to, they could do with starting it soon.
That is the first step.
The other stuff will come later anyway.
His link up play and passing is erratic, not shite. As for Osman's chance he plays a nice first time lay off to Naismith and peels away which opens up the corridor to play the pass. Other times, the idea is there but the execution isn't. I'd rather he tried the right idea and fail, than never try at all, as with practice it should improve and we'll be the better for it when it does.
For hold up play, his technique is poor. He shows the ball too often to the defender who only has to get a toe on it to have done his job. He needs to have more of his body inbetween the defender and the ball. He also needs to control the ball sometimes with his right foot. He passes and shoots with his right, so there's no "one foot" issue here; just confidence/application.
These things can be worked on though.
He definitely does need to be more aggressive though. As the article mentions, his debut at West Ham had everything in it that you'd want from a striker so it is there.
The big thing though, is that we've signed him on a 5 year deal.
All of the above don't suddenly have to be there 99% of the time, starting from the next game.
They won't be as they weren't all there last season either.
But sorting his dynamism out is the main thing, right now. Get that back and he'll still be scoring goals at a very good rate, even if nothing else improves this season.
