"It's just a case of turning up and seeing what happens, really. It is up to the manager what team he goes with.
"It will be a very special occasion, definitely not quiet.
"It's a stadium with a fantastic atmosphere and for a Scotland v England match it will be a very different experience to anything I've ever experienced.
"It will be something different to what I've experienced but it'll be a fantastic game.
"It is all about Slovenia, really, and looking at them first and foremost."
