Whilst I still agree that the best chance of scoring against them comes from pressuring the centre backs because they have the least technical ability and are most likely to make a mistake, the whole system is designed to prevent this from happening. First of all, they use the goalkeeper as a legitimate player to take the ball in normal play, so unless you want to play rush keeper and have them join in the pressing, that creates an immediate numerical advantage and thus an open passing option. Secondly, if you do pressure them high up, they simply run away. They stretch the pitch by putting players as close to the corners/sidelines as possible, which gives wider angles for passes making them harder to cut off. It's really quite lame, but unless you take a risk by committing half your team to pressing two players who might very well play it through you anyway, there's not much you can do about it.
