Advice needed

I have just bought the plug n play version off E Bay (Without instructions). After having a game with my 7 year old lad we know the A button is for shooting and long passes and the B button is for short passes. What is the C button for? Also any hints and general tips about the game would be great, Cheers

Are you saying there there is no instructions :-\-\, fair enough. My guess was the C Button was for headers when the ball rebounds off the keeper. At the moment it just seems to do the same as the B button. Anyway I need some practice as my lad was running rings around me, any tips would be great though to give me the edge over him, Cheers.
