Line up for tonight?

With a lot of our best players missing due to injury (and being on the verge of leaving) I feel this line up will give us our best chance of winning:

------------------Szczney--------------
Sagna---Djourou----Vermaelan---Traore
------------Frimpong------Song------------
-Gervinho-----van Persie-----Arshavin
-------------Walcott-----------------------

Reasons being:
Most importantly we have come here to defend a one goal lead, such a line up will make us defensively strong. I feel Song's quality defensively will be able to essentially 'cover' for Traore, who is likely to find himself out of position due to his relative inexperience.
This will also give us both pace and the technique to match in the counter attack, van Persie who usually plays up top (to good effect) could well find himself 'in the hole'. I feel he should play there instead of Aaron Ramsey, although 'Rambo' WILL be an incredible player, right now however, I feel he is short on confidence and therefore not attempting the through balls required to unlock defenses. Therefore, it may be worth giving van Persie, who has played that role a few times before eg against wigan in carling cup last year( http://www.youtube.com/watch?v=vcuwDsbAMA4 )a go there.
Finally, this would allow fluidity in attack, should this not work, Walcott can swap with Gervinho, or Arshavin may move to second striker, with van Persie moving to striker etc.
