Start by playing a few single player FUT matches if you need some currency. Then, search for a player in the transfer market by selecting a low price and other factors and pressing
. Bid for them or purchase them at full price. You'll probably have more than enough to do the latter if you've played a few matches. The FUT catalogue has a special contract package. Press
, to access the catalogue and find it, just like you would for the main game. When this package is applied to a player, they can play for 99 matches. If you have atleast a 1000 coins, then this is enough to purchase a player and a large contract pack. A player can easily be purchased for 300 coins or even less, and the contract pack costs 700 coins. Now enter the single player FUT lobby. Edit your lineup and insert your transfer player. You only have to do this once. Then they'll be available until they run out of contracts. Then, play 10 matches with them. As neeker75 said, you can forfeit the games if you want, since this counts as an appearance for the player. The achievement will unlock immediately upon starting the 10th game. If not, then play another game or two, as it's easy to lose count.
