Assuming we can find 11 players to start the game, then I genuinely do agree with you.
They probably feel like they've won the tie right now - an early goal in our favour in front of a packed and noisy Amex and you just never know. We've never done things the easy way before, why change the habits of a lifetime now?
It is of course important but even 1-0 at half time, Wednesday will still be favourites. If we have 11 on the pitch we'll still have bugger all on the bench!
