That's why I find people saying "Pardew is the new Souness!" are just morons. Souness had a complete disregard and blatant lack of interest in tactics and systems. Whatever you think of how Pardew sets his teams up, and the tactical tinkering he sometimes does, you can't accuse him of being not bothered about formations and systems etc.
I don't get why Souness seemed to think that players working hard and players organized into a certain system were mutually exclusive, they clearly aren't and clearly will work best in tandem.
