Arsenal, of course. Though scoring with Henry in this game is ridiculously easy even on the hardest setting

. Then again, Jens Lehmann in this game is about half the time as dumb as a rock, making great saves on hard shots, but missing a bunch of easy ones. Not to mention Theo Walcott turns into an amazing player also, along with Adebayor and Van Persie.
If you're looking for roster patches and stuff, I suggest using
http://www.fifakorea.net, though you'll have to make an account there though(but it's fairly simple, not like you'll have to do anything else after to download). The home site is in Korean, but you just have to click the English option thing on the top. They have a World Roster Patch that they made, or this huge gameplay/roster patch (adds some additional leagues, makes player growth more unpredictable (ie. young elite players will sometimes go down after a season to make it more realistic, like a player having a bad year or something) made by some other guys on it, this site can link you to that huge gameplay patch.
