It will also impact the Carabao Cup QF if we're still in at that point, and I would imagine the Crystal Palace league game which is pencilled in on the 16th Dec. Potentially be able to reschedule a CCQF to the free week before the Semi Final 1st leg at the beginning of January.
The semi finals of the World Club Cup will presumably take place either Monday and Tuesday, or both on Tuesday. I would imagine that means we cannot play Palace on the Sunday, and ideally wouldn't play on the Saturday either given the travel time. We could feasibly play Friday night but we have a champions league game the week before so would have to get UEFA to ensure the final group stage game is on the Tuesday.
I wouldn't be overly surprised if they postponed the Palace game too, to make it easier.
