FIFA 10

UPDATE: The servers shut down for this game on December 6, 2011, so now the only way you will be able to get this achievement 100% legitimately will be in local co-op.

There are a couple in-game glitches that allow you to pop various achievements even when you didn't meet the requirements for them. Since these are in-game glitches, it is not a bannable offense by Microsoft or TA. I won't go into detail about the process, I'll merely link to the thread that already describes it well:

That being said, if you want to do this 100% legitimately here is the two (or three) controller method:

Start up an exhibition match with two (or three, if you have them) controllers. This is possible with two but is easier with three. The extra controllers do not need to be signed in.

Make the controller signed in with the person who needs the achievement on a good team. I chose Barcelona (Liga BBVA). Make the other controller (or other two controllers, if using three) on the other team. Make sure the other team is bad. I chose Galway United (League of Ireland).

Make the game 20 minute halves, and make sure bookings are on. Also make sure that auto-switching is set to default (I believe the bar is halfway at default, playing with auto-switching higher would probably work but I haven't tried it).

Make both teams ultra defensive (press left or right on the D-pad to adjust defensive/offensive playstyle).

If using 3 controllers: Get the bad team control of the ball on on their side of the field. Take the controller on the bad team without the ball and go find a player on the good team and press x while running in to him to tackle him. If you are lucky this will get you at least a yellow card.

If using 2 controllers: Get the good team in control of the ball. Use the bad team controller to go after the controller with the ball (or someone without the ball if you can before you are auto switched) and press x while running to them to tackle him. If you are lucky this will get you at least a yellow card.

Repeat this until you have 4 players on the bad team (DO NOT exceed 4, or the game will end) with red cards and are sent off (2 yellow cards = 1 red card). You now have a very good team with a 4 man advantage against a very bad team. Make both teams ultra-offensive and press pause to select team sides. Switch the second controller over to the good team (if 2 controllers) or one of the two controllers over to the good team (if 3 controllers). The game will give you a warning about not making progress towards achievements; ignore it.

If you used 2 controllers, you are just going to have to make runs at the the goal up the sideline and constantly hit x (with your primary account) to send balls in front of the other team's net via a cross. You will have to quickly switch controllers while the ball is in the air to your second controller. The game will auto switch the second controller to the player closest to the ball, so don't worry about that. This is going to take a lot of tries, but eventually you are going to get a good cross that goes to your second controller and will be able to press B to head the ball in or otherwise kick the ball in the net (This is why halves are set to 20 minutes - this is going to take quite a few attempts, you may not even get it your first try, but this is the best way to attempt it with 2 controllers)

If you used 3 controllers, get the bad team possession of the ball and cause a corner kick for the good team. The kicker will alternate between the player you want the achievement for and the second controller. If you are kicking with the player you want the achievement for, just kick a normal corner kick into the middle of the pile in the front of the net and quickly switch controllers and attempt to head the ball in the goal. If you are kicking with the second controller, just do a short pass to a player right in front of you and have them do a cross into the big pile of players. I managed this after about 15 minutes, including the time it takes to get the 4 players sent off.

If you want to make this method even easier, you can edit the good team to make them even better and the bad team to make them even worse, by way of adding created players to the teams and making them starters (in addition to stats, don't forget height - this will help you in headers), but in my view you will get the achievement faster just playing with default teams than it will take spending all the time editing players. I would only recommend this step if you are having particular trouble with the achievement.

This is, of course, is also much easier if you actually have other people controlling the other controllers so they can aid you and/or screw up the opposing team, but is still very doable by yourself.

Cross for a friend, sounds easy right ? Harder than you may think. Set up an exhibition match with you as a team thats good at headers, i would recommend chelsea put ballack, drogba, alex, terry etc... as forwards and set crossing to manual. Play a team like accrington or any worse you can find. run as close to the keeper as you can and get your friend to find a position in line with you, Tap (X) and your friend should volley or header your "cross". Keep trying until you score and remember to have manual settings on for crosses.

Good luck

Got this while playing Pro Club Championship, I for whatever reason was selected to take a corner, put it straight at a 6' 7" teammate and he buried it with his head in the net, he was not on my friends list so I can confirm it doesn't have to be a person on your friend's list. Corners are the best time to do these because all your teammates will be looking for the header, just keep playing online team play, preferably as the manager so you can make yourself the corner taker, and you should get it in a few games, keep at it and you should get it.

If you're having trouble getting this, I can confirm that it does unlock in online team play using your Pro player. Choose a position out on the wings, and whenever you get the ball (if you ever do, people tend to be far too greedy in online pro matches) hit crosses into the box. If someone gets on the end of one to tuck the ball away then ding! Achievement unlocked.
