I work at Lancs during matchdays!, doing 1 of the most important jobs, scoring the match (cricket match) for the Replay Screen so I was a little pissed off when America scored right at the end today which means I won't be able to give my full attention to the football otherwise I will cock the score up.
I can't answer the question regarding whether they will show the football, personally I cannot see it. During England matches the ECB control a lot of what goes up & they usually show replays & advertisements & also of course the cricket scoreboard so the only thing I reckon they would do is do score flashes ,their won't be time for anything else.
A few years ago a screen was erected near the nets but with little time scale left until Sunday again I would say this would be doubtful. The best bet would be to watch it outside one of the bars underneath the stand or in the Pavillion, they SHOULD have it on. You also should be ok leaving the ground & coming back, they usually give you a passout & providing you don't loose it you should be able to get back in no problem. Don't quote me on any of this though this is just what i think MAY happen.
