One thing that football fans absolutely love to do is come up with their own formations and styles of play for the sides they follow.
These line-ups range from the surprisingly effective-looking, to the shockingly bizarre.
Never more has the question of how Sir Alex Ferguson should be sending out his players at the start of a match been more of a hot topic than it is right now.
With the addition of both Shinji Kagawa and Robin van Persie to the Manchester United side, things have been drastically altered in regards to the first-team hierarchy at United.
It isn't often—in fact, I can't recall any example in recent memory—that Fergie has brought in two players in the same transfer window that shot right to the very top tier of the United dressing room in terms of pedigree.
Having two players of this standard come in is both a blessing and a curse.
Obviously, it's fantastic for any side to have as many world-class talents as possible coming out in their colours every weekend.
However, it does (initially, at least) cause a nightmare tactically for a manager, who will always be more than likely forced to drop a regular first-teamer in their place.
So how many new formations does Fergie have to play with now? And can they incorporate all the "best" players?
