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.
Teams that are tired of the Premier League and European matches being played together and this intense fixture should make good use of this break. I'm sure no one likes to play in so many intense and compressed fixtures. After the Premier League starts, we will better understand how the players are making use of this break.
