Is the area you are experiencing pain different from the area you had circled in the image posted above? More towards to the toes, on the top of the foot?

If you don't have pain with running or walking, and you only experience it with kicking, then the chances of it being a nerve impingement or tendon problem (tendonitis, tendonosis) or stress fracture is unlikely.

I have to admit, it's hard to say without an examination of your foot. Can you localize the area? Do you have pain when you press on the area, when the shoe is on? when the shoe is off? Any redness, bruising, swelling?

It could be an impact injury from the ball contact on the foot, which probably wouldn't improve until the off season, but wouldn't necessarily be damaging to continue to play on (but I would expect some swelling, possible bruising). A poor fitting cleat with the laces bunched up or the tongue overlaping too much, where the ball has contact could cause a bruising type injury. Overtime this could result in pain with pressure even without swelling or bruising.

The last problem I can think of would be hyperflexion at the joints in the midfoot as a result of the impact of the ball and due to a lack of stability in the foot (either ligamentous or tendon). An X-ray and exam would be needed to diagnose this.
