There are some team sports that are "strong link" games; that is, one amazing player like a LeBron James or a Michael Jordan can hold up a team that is otherwise only decent, and shepherd them to victory. Other sports are "weak link" games; that is, one bad player will let the other side score, or fail to hold up their end. Soccer, or football as it is known in the land of its birth, is a weak-link game. This means that it's very important for the team to work together to cover one another's weaknesses, boost one another's strengths and understand the overall strategy.
This means that different teams tend to develop their own cultures that transcend any individual player. A star player, even one as big as David Beckham or as talented as Cristiano Ronaldo, cannot simply swan in and dominate the scene. Only the manager has this sort of power, and even he will tend to be hired in the image of the team. The result is that different teams tend to develop very strong and varied identities, and this affects who supports them; unlike Major League Baseball, which footie team you love tends to be about the one with whom you identify as much as it is about location.
Thus, picking a team on which to play is all about culture fit: how you train, how you see yourself, what sort of fans you'd click with, and who you are. Tell us a little about yourself and we'll find you the perfect Premier League team!
