positioning

I'm doing my 7-6 and there's a section on the assessment about optimum position at kick off I've got my first coach visit in the new year so I'm just wondering what the best position is.

Has anyone got any tips for positioning when play is in the middle? I feel like I get in the way and caught up in play way too much when the ball is in the centre circle in particular.

I'm approaching 10 games in the middle and by far, the biggest thing I need to develop is my positioning. I think I struggle usually when it is on a smaller pitch and sometimes find myself too close to the ball. What's the best bit of advice to improve my positioning. I'm certainly not a referee...
