I've mainly been Barcelona (annoying I know), but occassionally I go Netherlands because they are a pretty good team too.
FIFA still pisses me off unbelievably, but I had my very first game in Division 1 last night and was against a very tough, skillful player. He chose Bayer Leverkusen, and was very good on the ball and defensively. He was allowed by the ref to completely go through me and I never really got any fouls despite some blatant fouls, it's something I have yet to properly master in-game as it seems legal in EA despite clearly being illegal in normal football. Anyway he got a bullshit penalty kick, hit the post - but then scored soon afterwards, to be winning 1-0. After that though I put in a pretty good game defensively, and was able to prevent too many real chances for him. It was down to me being able to find a goal - and to my shock I equalised soon afterwards, a lovely lofted through-ball was headed into the bottom corner by Iniesta. Second half, more of the same, until I release Fabregas down the left, he is given space and time and I make the most from this to score at the near post - I couldn't believe my luck because this player was very good against me. I held on for a big win.
Playing a lot of custom head-to-head games to try to improve myself defensively, so I can stop raging at EA's bullshit.
