How should arsene be line up their team

This is good news for arsenal after they got arshavin last night, witch is a good for both sites between arsenal who desperate to find a consistent player and arshavin who dreams to play at arsenal.

With Arshavin's arrival taking place, I've started to think about his potential Wenger targeted. Having strained my brain, I can't think of any realistic possible formation.

As we know, arshavin is a world class player who can play in position midfielder and a striker. Right now i'm sure he will be take fabregas part or adebayor who really not consistent in this season, which case arsene should think about it after fabregas, aduardo and rosicky back`after injury.

However, how should be arsenal line up their team after they got this man, if arsene would use the same formation like 4-4-2, i think is okay. but maybe they should try a new formation 4-3-3. as well as we all know they already have adebayor, van persie plus a new star player arshavin.which in maybe they will play much better than before if they take new formation 4-3-3, whose know about it.

In my opinion ,this is how i would line up the team with our current available squad.
almunia , sagna , gallas, toure, and clichy as defender. rosicky (walcott), fabregas(diaby or denilson) and Nasri as mifielder. van persia, adebayor (center) and arshavin (left).

Whatever arsene takes his team we hope they will gonna be alright. and we as a fan really hope arshavin will shows his potential to help arsenal archive something for this season.
