Earn Money For Free
Buy a young free agent with overall at least 77-80 play with him for 1 season sell him for a big chunk of money.
Keep track of your finance in Manager Mode in Manage Club. It will tell you your predicted finances for the rest of the season and in it's different areas. (Don't make the same mistake that I made, I thought I would end up with that money at the end of the season).
Start manager mode with a club like Man City or Real Madrid(a club with lots of money). Buy the players you want and sign them on one year contract. Complete a season and resign. Choose another club. Go to transfer market and free agents and sign the players without paying the transfer fee.
A shot at goal doesn't always have to be powerful to get past the keeper. The angle of the shot and the approach are more important factors. Try not to approach the goal straight on.
Make Lots Of Money Really Quickly And Easily
After you have completed your first season. Sign AS MANY free agents as you can be bothered to sign. Offer then the maximum wage that your club will allow you to. Play one match. You will have signed all of the players you offered a contract to.
Then put them all up for sale and accept all offers that come in for them. I usually gain about 35-40 GBP million each summer doing this.
For a Penalty Shootout, put all your attackers in and swap then with your defenders. If you are in a match situation, make the substitutes during extra time.
