Don't think the Fulham result has any bearing on Thursday whatsoever. We're a team that can drop a stinky performance one week and look like world-beaters the next. Liverpool made us look like a Championship side earlier in the season before we did the same to Bouremouth. I'd be concerned if we're in a vein of poor form, but we where unbeaten in 6 before the weekend.
We're a better team then Forest, if we play to even 70% of what we're capable of, we'll be taking a level scoreline to VP at the very least.
