"The pitch at Don Valley was much improved towards the end but we all know the problems there have been down there since the U2 concert back in August," said Moore.
"Wembley has taken some 'stick' over the surface and they've kept relaying the pitch but it didn't seem too bad at the England game the other night.
"But, whatever it's like, we know we'll have played on much worse this season so no-one will be getting uptight about it. It won't be bothering us; it's not as though you've been on a perfect surface all season and then come to a dodgy one."
The Millers travel down on Friday Morning and are due to take a look around the stadium in the Afternoon. Moore added: "That gives us a feel for the place. The lads will have their cameras out and get all the photos they want tomorrow, None of that on Sunday; that's for football."
The players will also take in the League One playoff Final on Saturday, between Millwall and Swindon Town.
