Yesterday was the first soccer game. I went with my 70-200mm f/4 VR coupled with my 1.4x TC which is all I wound up using. I also took my 300mm f/4 PF with the 1.7x TC attached but didn't need it.
The 70-200mm plus 1.4x TC worked really well. I really wanted images that were closer to the action and not so much showing the entire team playing. I stood on the same side the boy was on but closer to the goal. That position worked okay for some of the time. The problem was the action tended to be more towards the center of the field making me see more of his back than his face. I did wind up with some of his face, but I don't want to post those. Next time I will try standing on the opposite side close to his goal in hopes of seeing more of his face.
Most of what I edited were cropped. All but a couple were shot in horizontal format which allowed me to crop vertically if desired.
Here are a couple images.
