Well I am really looking forward to this one both teams are going in to the match in fine form. It will be a dilemma for both coaches, do they alter their personal to deal with potential weakness's that the opposition may exploit or do they let the opposition worry about them and stick with what has made them successful so far.
Germany's midfield had the better of England and this may give Diego and his team food for thought. It would not surprise me to see some support for the chief, in an ideal world Cambiasso could have offered this but without him in the squad they may bring in Veron in a diamond similar to what they did against Nigeria.
I wouldn't be surprised to see Maradonna bring in a wild card and Mario Bolatti could offer Mascherno some support and he could bring on Veron later in the game when an older more experienced head is needed.
I would expect as Germany's strength has been they have a settled way of playing with Klinnsman/Lowe and then Lowe there not to be too many tactical changes. Although Milner got plenty of space against Boateng and if Tevez drifts into that position I feel he will cause problems.
Then there is Messi and Ozil be interesting to see what either team has in store for them.
