Above you, on a small stool is the eye of your coach. He's really high above you though, and all you can make out is the glint of his eye as he perches on that stool. But he's yelling out orders and corrections, which you can hear very well.
You finally win the big game and the coach is coming down off of his stool, and you see that's he's the ghost of Tokugawa (とく) Ieyasu!!! That explains why you could only ever make out his eyeball!
