For an absolutely worthless post pondering the variables we should consider for this match, or in other words, what Capello will not do..
The simple way to beat Arsenal is to cut-off their rhythm in midfield and suffocate their movements on the pitch, something that requires hard work and holding lots of posession. A team such as Milan would be the perfect side to beat Arsenal, considering they do not let the opposition have much of the ball and hault their opponents in midfield with copius amounts of pressure and posession. We will need to emulate these tactics against Arsenal because if you run them over they will simply be choked. The fact you cannot let Arsenal control the tempo really applies to all English sides you'd face..
Buffon
Zambrotta - Thuram - Cannavaro - Balzaretti
Emerson - Vieira
Camoranesi - Del Piero (Nedved) - Mutu
Trezeguet
It's a real shame Nedved is not available for this match because I would place him right behind Trezeguet and make sure he comes back in midfield to disrupt any sort of influence Fabregas has on the match. Nedved, if on form, would cause Silva and Fabregas to come back deeper and thus hault them from going more forward. The deeper Emerson would pick up the darting Hleb and Vieira would roam around making sure everything is tidy in the center of the pitch. The last thing I want is to have Hleb or Ljungburg or Henry run at our defense with options because our straight four midfield was caught out. And with Nedved just running around like a headless chicken it would disrupt the Gunners enough in midfield to throw off their rhythm a bit.
Camoranesi and Mutu would expose the weaknesses of the Arsenal fullbacks and if we have enough of the ball we will undoubtedly beat their defense some point in time. You simply take the game from Arsenal and do not let them play...you force them to commit errors and don't let them get even a scent that you will give them any space. Make sure Henry gets roughed up and knock him around and dont let him have any space at all. This is all easier said than done, obviously, however the writing is on the wall what you need to do to beat Arsenal.
Will Capello follow any of these ideas? Nope. And we shall see how we fair with such generic tactics.
