Can't remember Soccer MMORPG game.?

I played this online MMORPG-styled soccer game like a few years ago. The graphics weren't so realistic but more cartoony. You could buy, trade, sell, level up players throughout the game and with players around the world. The players had 3 strengths: Striker, Defender/(tank), and something else i cant remember who would run fast... and if the player had fairly high and balanced strengths, they were considered to be an 'elite'. So basically, you could play soccer matches and train but also manage your team. Another thing, the Defenders were BIG, slow, macho-looking avatars, asides from the other two positions who were faster and thinner. Remember, it was not a realistic-graphic looking game like FIFA. So if anyone could give me some names if they might know what game i am talking about please answer. Thanks -John
