You don't even have to win the games, for this achievement! Just keep the ball in the middle of the field an pass it through.
It helps, if the CPU's difficulty is very low, since they won't attack you as fast. Keep the ball long enough, and you will easily get a percentage of over 75-80 for ball pocession.
Another tip: I recommend doing this in 5-minutes-halftime matches, since it can be really boring.
