#2 Gilberto Silva
Gilberto Silva wasn't skillful enough for a typical Brazilian player and wasn't much of a goal hunter but his contributions were priceless during Arsenal's unbeaten season. He was not a goal-scoring midfielder but a defensive one, calm-headed and a natural leader.
Gilberto Silva was a fantastic servant for Arsenal during his six years with the club, and really should have been made captain over William Gallas when the role was vacated by the outgoing Thierry Henry in 2007.
He formed an integral part at the heart of 'The Invincibles' and the Gunners' incredible feat may have still remained a dream if not for his contributions.
He provided mobility to the side and gave license to the rest of the team to surge forward en masse. Unfortunately, the man just doesn't get the credit he deserves for his role in that side.
