Pro Evolution Soccer 2012

See The Debutant for suggestions of shortening the time this trophy will take to unlock.

If you followed the suggestion I made above about using an actual player, then this trophy shouldn't pose you any problems. If you picked Lionel Messi, then advancing the date a certain amount of time should allow you to see how well Barcelona are performing, odds are they will be relatively high in the league, you may need to play a few games to ensure they are crowned league champions.
