I use the CPU press button quite a lot, against humans on XBL too, like pboreham says, I use my controlled player to jockey / cover space and then get the CPU to harass them like mad!
Thanks for this (and other contributions yesterday) in the one quick game I had it seemed to work well. I had to move the player switching down to very low though otherwise as I'm trying to use the CPU to hassle I was finding it was auto-switching to me :-)
I tell you a big (and positive) difference on this game to any other I have ever played is I'm just happy to get a win now. The whole bigger picture is now felt more due to the atmosphere etc.
I had a qualifying game against Northern Ireland at Wembley and I won 1-0 but rather than pressing for a second, and a third, as I would have done in FIFA08, I was happy to sit back, soak up pressure and try and catch them on the break.
There's just so much more game intelligence now and it's bloody great.
