I know this is and old game but seems I recently won this achievement and there was no solution to it, I thought I would try to help others out.
To get this achievement I started a new game with Australian league only (to make simulation go faster). Selected to manage England, then simply went on holiday and waited for England to qualify for Euro 2008 as the World Cup 2006 qualifications have already started when you start the game. Any major European nation will work (just don't choose Greece as they get a bye to next round due to winning Euro 2004....).
Turning off autosave under preferences from the main menu will make things move a little faster.
