And I think thats the frustration. I understand that time is needed to be on the same wave length when it comes to linking up with attacking players as you pointed out with that Isak example. I think most reasonable people dont have an issue with those miscues.
Its all the other stuff that I mentioned that are a frustration, something only he alone can influence now. Aside from the running (and he does a lot of it, and works hard) hes got to show some improvement in those areas.
If the players arent making runs, start taking a pop on goal, at the edge of the box or inside the box. Be more ruthless in the box, not everything has to be neat and tidy. If you're going for ball, put some umph in the shot, etc..
