Argentina look crazy going forward and a little bit vulnerable at the back, especially on their right flank. I expect games with them to be exciting end-to-end contests and well worth watching.
The first is the right flank. Aaron Lennon/Shaun Wright-Phillips have this tendency to run down dead-ends and/or provide no end product. Seriously thought that Adam Johnson should have made the squad because he actually has the ability to beat his man and then do something with the ball. And then, dum dum dum, Glen Johnson. If Landon Donovan runs down that flank tonight, be scared. And this is Landon Donovan. Imagine Messi running down that flank. Or Ronaldo. Or Schweinsteger. Or Silva. And then, they don't really have any depth. And if Rooney gets injured, goodbye World Cup.
I think problem 1 is resolved by problem 2. The reason why Glen Johnson is a bad defender is because he is a good attacker and creates lots of attacking opportunities down the right flank. He really should've been a winger rather than a full back. I think against better opposition England should get someone more defensive minded in the right back position, but well, who else is there? Carragher is a good defender but not the most mobile of players, I can see him getting caught short too.

also btw, message to all the filthy yanks: if England lose and anyone who hasn't posted in this thread before shows up gloating, I will be taking out my rage on you by renaming you after 90's footballers. Just a warning so you can't complain when it happens.
