Cropped Using Rule of Thirds
Though a difficult photo to use the rule of thirds (due to the large subject area), I was able to crop to make the focus more to the team.
Erased (but added grass)
Using eraser and the clone stamp tool, I erased a player and then cloned grass. You can tell it has been removed, however, next time I would clone the grass near their feet as it is darker.
Clone Stamp Tool ( How many players are on this team?)
Using the clone stamp tool, I added more players than there was in the original photo.
