As of 8th February 2011, the online servers have been shut down so it is impossible to gain the online achievements. That means that for everyone that doesn't have any of the achievements listed below, this can never be officially completed. The achievement descriptions are below the achievement themselves.
Complete a ranked or unranked match with the lead FIFA Street 3 profile on Xbox LIVE.
For this achievement, all you had to do is simply play and complete a match on either Ranked or Unranked Online.
Complete an Xbox LIVE match against another player who has Street Fever with the lead FS3 profile.
You needed to play against someone who already had this achievement to unlock it. Most of the online community had this achievement on their card, which would've made it easy for you to unlock.
Win a completed match as the host of an Xbox LIVE Playground Picks match with the lead FS3 profile.
To gain this achievement, you had to host and win a Playground Picks Match Online, which was easily boost-able with another player.
Win a completed Xbox LIVE Playground Picks match hosted by another player with the lead FS3 profile.
To unlock this achievement, you had to join and win a Playground Picks Match Online, which was once again easily boost-able with another player.
Score 50 goals in completed ranked matches on Xbox LIVE with the lead FIFA Street 3 profile.
This was very simple to obtain, just score 50 goals in Online Ranked games, but if your opponent quitted all the goals scored in that match would not have counted towards the achievement (same issue as with FIFA10). This was, again, easily done with a boosting partner. You had to actually score 50 goals as you couldn't get your partner to score own goals as these would not have counted towards your scored goals.
Complete and win 25 ranked matches on Xbox LIVE with the lead FIFA Street 3 profile.
Again very easy if you had a boosting partner since you could've just taken turns for winning. First of all, this had to be done in Ranked matches. It doesn't matter if you won in a regular World Challenge-match or a Playground Picks match, as long as you finished the match with a win. Also, it would've been easier to track your wins if you kept playing the same match-type; as your wins were shown on the leaderboards. You had to be sure not to quit out of the matches, since quitting out didn't count towards either your or your partner's achievements.
