Build a team with synergy between the players, so they will perform better together.

If you bring in a star but he doesn't work well with your other players, you're better off selling him..

When you complete a match, whether you win or lose, you'll receive virtual currency called FCC. This you can spend on Ultimate Team boosts, which can include a variety of benefits.

With proper boosts, you can earn an extra 1000 coins or so every 10 matches played in Ultimate Team.
