I dont have a six button controller and as you can probably tell its an unbelievably bid disadvantage, how can i get around the problem without buying a new controller?, i'm sure lots of you have this problem as well.
It takes away alot from the game as well as making it much harder to attack etc.
I have to be able to do skill moves!

You r just whining or asking help for how to make skill moves with the keyboard?
If its the second option then try this:
ALT and CTRL r the famous skill keys,
press this keys and try many times with each normal game button as pass, shoot, foul,etc:
Now, if u press ALT+CTRL+normal key u may send your side defenders to attack by the line, or sent a man to the area.
And finally, if u r about to shoot a free kick, u can use ALT or CTRL for a "banana" shot.
