|Career mode: Good team|
Create a club in Manager mode with the maximum budget. Create fifteen or sixteen players with maximum attributes. Set their birthday to 1990 so they are very young. Build only as many players to have only the minimum for your squad to be ready for your created team. You will now have an invincible team in Career mode. If you do not have many players you will not have to pay a lot of money to them. Try to give them as low of an amount of money as you can to accept.
Manager mode: Cheaper players
Have the transfer window is open. For example, if playing as Manchester United, put Tevez on the transfer market. Negotiate for someone like Eto'o, who is better. If you get him, something will appear if someone bid for Tevez. Let Tevez go because you have got Eto'o. Instead of paying all that money for him, you are only losing a little bit.
Give the ball to C.Ronaldo and sprint from midfield towards your opponent's post. Press [Sprint] and take three steps then shoot the ball. The power of the ball should be almost full.
Most achievements can be unlocked in multi-player mode. Achievements such as the ones for penalties, the switcheroo, the various ones for scoring and the giant killer are a lot easier if done against a human player.

* Have the transfer window is open. Search for good free agent players with at least skill level 75 and below the age of 30. The more skills with younger age, the better. Sign them and offer them the highest wage you can. If your negotiator skills are low, the player you try to sign will reject your offer. Try to re-sign him with a higher offer. For example, if the player wage is $35,000 the first time, the board will only allow you $45,000 for the player. The player will reject any offer below $70,000. When you re-sign him for the second time, the board will allow you more than $80,000. You can now sign him. When the player is yours, change his status to "For Sale". Big clubs will be interested in him and you can get a lot of money. If you manage a small club with a limited budget, do not keep this player. Otherwise, you will not have enough money for other players.
* In Manager mode you will have a 90+ overall team. The Youth Academy in your office will have youth players of about 70 at the age of 15 or 16. You can either play with them throughout or sell them in your fourth of fifth season to earn millions of dollars. Try this with J. Baxter, Rodwell, Bunce, Morris, etc.
If your player is injured and is out for too many days, you can speed up his recovery. Use the player as a sub while he is injured. He will suffer another less serious injury, and should heal in about a week or less.
For clean sheets to be credited in season, tournament, Be A Pro Season, manager modes (everything outside exhibitions), it would be the final keeper present at the end of a shutout (clean sheet) game. For example, if you start with Edwin Van der Sar in the first half, Thomasz Kusczak in the beginning of second half, but finish with Wayne Rooney in goal because Kusczak was red-carded, and the final score was 2-0, Rooney will be credited with the clean sheet, and not Edwin Vander Sar. Kusczak is ineligible because he was red-carded. The clean sheet is void if any goals are scored against them. If any keeper conceded a goal, any substitute keepers in goal will not benefit even if they didn't concede any further goals.
