but but in the last few years we ALWAYS had to rely on one particular player to steer the team forward. The Invincibles were all around squad, each player played their role with no one taking the 'God' role. after that we can see the pattern started to change to one-man team a.k.a. the God role who ends up being snatched away by other teams:

post-Invincibles:
when the Invincibles broke up; Pires, Cole, Vieira, Parlour, Edu, Bergkamp all left the team, we became over reliant on Titi - he's the captain, free kick taker, corner kick taker, penalty taker, top scorer and providing top assists as well

post-Titi:
after Titi left, Wenger started to build new team with new set of players AROUND FABREGAS. the pattern repeated itself - Fabregas became what Henry was except that he scored less (but I think in one season he was our top scorer no? forgot already)

post-Fab:
again, the same thing happened. this time it's RvP. and look where he's (probably) heading now

we don't know what's in Wenger's mind but seeing his actions in the past I think it's not impossible that he is going back to square one and rebuilding the team again should RvP leave, which is really bad for us because if he keeps rebuilding then how the hell is the team supposed to get matured and ready to challenge the Mancs?
