I don't think there are many teams that can match Liverpool's pressing. It's consistent, everyone knows what they are doing and they know what to do with the ball when they get it back.
However like you said, most of the top teams try to play their own game and don't adjust to this sustained pressing, hopefully Mourinho is aware and stops us dithering with it at the back but a lot of teams won't realise until they are 1-0 or 2-0 down.
If teams play it a bit more direct (not necessarily long ball) and most importantly shift it around quicker then any team with this kind of pressing will naturally tire.
I suspect a lot of teams won't realise what hits them when they face Liverpool and the fact you don't have Europe gives you added rest between games which is perfect for your style of play.
