It will be interesting to see how we line up tomorrow night. Injuries to Almunia, Gallas, Song and Arshavin see Arsene's options severely limited. The real problem for me is the missing Song, as it this area where we really lack quality cover. Obviously Fabianski and Campbell will come in at the back. Now I shall digress
If I were Arsene then I would be tempted to switch to a 4-4-2. I'd play the obvious back four, then Eboue could play a slightly roaming role on the right of midfield, with a license to drift inwards a little to help out the central pair of Diaby and Cesc. I'd then slot Nasri on the left, then a front two of Eduardo and Bendtner would do nicely. I am not Arsene and many of you are very thankful for that, so I suspect he shall stick with 4-3-3, Denilson will come into the midfield, it really is make or break for him now, I would then guess that we would see a front three of Theo, Bendtner and Nasri.
This is a big game in many ways, not only does a lot of our season hinge upon this cup competition but if certain players do not step up then there will be some rather big question marks hanging over their heads in the summer. Porto will make it tough, they will be useful in possession as always, the most important thing in my opinion is that we go there to win, we must have enough men up the pitch so that we do not simply lose the ball because our lone striker is too isolated, we must attack, attack is the best form of defence especially when one isn't that great at defending.
