How Arsenal will line up if Fabregas leaves
Wenger can also decide to play Andrei Arshavin in that position as this is the role that made the Russian assassin flourish when playing for Zenit St Petersburg and Russia. Another option for Wenger if wants to stick with the current formation is to deploy Alex Song and Emmanuel Frimpong as holding midfielders and move Jack Wilshere upfront. I believe with good grooming, Wilshere can be as good as Cesc or even better. The only problem is that, he showed when the Gunners played against Birmingham in the Carling Cup final, that he likes to control the game from deep. The plus with this is that it will ensure that the Gunners are more stable defensively as Song, Frimpong and Wilshere are all good defensively.
Should Wenger decide to switch formations and revert to the 4-4-2 style, then he can have a central midfield of Song and Wilshere and a strike partnership of Van Persie and Walcott or Van Persie and Gervinho. The former will give you glimpses of the unrivaled Henry / Bergkamp partnership. This will leave the Gunners with a plethora of players who can play on the wings: Ryo Miyaichi, Arshavin, Nasri, Rosicky, Walcott or Gervinho.
Alternatively, Le prof can decide to entirely change the formation. Yes, 4-1-2-3, a highly attacking system that was employed by AC Milan last season. Alex Song can play holding midfielder with Wilshere, Ramsey or Rosicky infront of him. And Van Persie, Nasri, Walcott / Gervinho / Arshavin can form the attack. This formation though very rewarding offensively, it leaves the team weak defensively and although Milan used it successfully last season, the Serie A’s attackers can’t compare to the EPL’s pacy forwards.
But trust Arsène to get it correct.
Keep the faith!
