Manchester United should have been ready for this match against Crystal Palace but because the death of Queen Elizabeth II made the match postponed, I think this is an opportunity for Crystal Palace to prepare the strategy used against Manchester United considering they are currently excited because of the process of recovering the standings league premiere.
Not only Crystal Palace, but all teams will definitely take advantage of this opportunity to prepare the team even better. It wasn't that long, but this time lag was enough to rearrange their strategy. Especially if the team's condition is not good, this is a good opportunity to rest and try something to apply when the game starts later.
It was enough to give time for all of clubs to think about their strategy against the next opponent. It seems like that some of clubs have been using this delay to take more rest for its players after the champion league match. Next week will become a very good time to watch any matches in EPL. It's caused by any team will be on fire after taking more days to rest.
