Thanks, have built my new 433 (4) team and have changed it from what I had initially because I found a way to change one of the CM's to Fernando from Man City, a M/H, thanks to a sneaky little strong link between Nastasic and Ivanovic. At one stage thought the only option I had in CB was Demichellis!
Haven't been countered too badly, no worse than any other formation. Yet.
