First from the Main Menu go to My FIFA 11 -> SETTINGS & PROFILES -> CONTROLS -> XBOX 360 CONTROLLER. Now on the first page of settings you need to turn Save Assistance to 'Manual'. Now start a Be a Pro: Goalkeeper Kick-Off match as any team against any team. Once in the pre-game menu you need to go to Game Settings and on the Be a Pro: Player page you must turn all 4 options 'Off'. Now you are ready to start the match and once you finish it and arrive at the post-match stats page then you will get the achievement. You do not have to win the match etc. and if the match ends in a draw after 90 minutes you don't have to play extra-time.
