Yes, they will definitely make the most of the time they have. Because as you said, maybe the club or player is not very ready to face the hectic schedule, especially for a club that plays in several competitions simultaneously. This was something that rarely happened, but they got it now. But on the other hand they have to replace the postponed matches and maybe for some clubs this is actually a hindrance if they are at their best.
Maybe this postponement will be good news for clubs who still have problems with team performance to be able to improve and take advantage of the delayed schedule to train more seriously, because the busy schedule will make it difficult for them to train longer and this is an opportunity and hopefully there will be changes.
however the postponement will leave football fans around the world a bit disappointed as the Premier League game is what they are looking forward to at the weekend, but they will understand that the postponement has occurred in honor of Queen Elizabeth's death.
Well in this case actually I'm not too bothered because I like some of the big leagues that are currently rolling like La Liga and Serie A so a few days off for the EPL is not too disappointing for me because this is also a tribute to Queen Elizabeth II so indeed I still don't really have a problem with that.
Regardless of the various perceptions that exist, we still have to look at the bright side and indeed with this there are some good things because at least big teams like Chelsea and Liverpool can breathe more to wade through the season.
