Make it interesting for yourself. Experiment with teams, formations etc. I rarely play with the same team again and again - unless I need to avoid relegation.
Think i have finally finished with Fifa for a few years!
Fifa 12 for me is an amazing game and i love it but i have got to the point were i simply hardly ever lose online, i have just won division 1 six times with out defeat. Thats to add to the 20-25 other division 1 titles i have, i often go 40-50 games unbeaten, there is no challenge anymore because i have become to good, this may sound great, but i have no reason to play it anymore. Im crap at COD though " />
