There will be loads of Scousers trying to sneak in, wait for a couple of others to try and do it and then use them as a distraction to make your attempt, as Ronnie says loads of fans from both sides of Manchester sneaked in last year, apparently it was harder for the CL final but you don't need to show your ticket until the turnstiles when the FA are in charge.
TBF - scousers are genetically programmed to try and jib in, even if they've got fucking tickets.
