From the main menu select 'Online' and then 'Quick Match Team-Up'.
After matchmaking you will be assigned a random player on a random team. Luckily you only have to finish one game but you might as well try to get the win. So once you are in the game defend your position as good as possible and play to your strenghts on offense. Pass the ball, take smart shots and hope your teammates do the same.
The achievement will pop a few seconds after you are back in the 'Online menu' when the servers have updated your stats.
Note: If everyone else quits out the game will end saying 'No remaining players in the game' so you need at least one other person to stay in the game until the final buzzer.
