La Liga's new season is in full swing, and Barcelona is atop the tables with a five point lead on their rivals, Real Madrid.
Tito Vilanova's side has yet to even hit full stride, but they have still gotten the full three points from every match so far.
That success is representative of a team that is considered the best of this generation. It is not because of any one player, but because of an incredible team effort.
I recently looked at the five least expendable Real Madrid players under Jose Mourinho, and I have decided to follow that up by listing Barcelona's five players who are the most important to the team's success.
La Blaugrana work as a unit and well-run machine perhaps more than any other team in football. The failure of one core player to do his job affects the whole team.
Almost every single player is vital because of how interconnected the ability of one player is to the rest of the team.
So when I list these five players as the most important, that is not to say that no one else is important, nor is it saying that the gap between these players is great. In fact, the five players on this list are almost equal in value to the team.
With all that said, let's take a look at the five least most important players on Tito Vilanova's roster.
