I know that, you know that, quite a few fans of other clubs would know that too.
Would Capello play him ahead of Barry? Not in my mind. I think that Capello would think the 'balance' of the side would be disrupted.
But Capello is a bit of a dick and probably has Barry written on his team sheet before anyone else - why else would he take someone who was still injured to the world cup when he was basing his picks on "form".
Also, he can't even speak English properly after being in the job for over 2 years - there's dedication.
Back to Arteta, you'd be proud if he was picked for England but at the same time wouldn't want it to happen really.
