Newcastle still need time to strengthen their mentality in the UCL. With this busy schedule, it can affect their performance in all leagues. Maybe they don't have any targets for the UCL this season, but being able to compete in the UCL is already the best experience to prepare for the next UCL. With financial strength, Newcastle will probably start preparing when they can become EPL champions. Because, if Newcastle can become EPL Champions, there will be a lot of top players who will be easier to sign.
Actually i personally not so surprised about Newcastle being able to finish in the top four, because in fact Newcastle has very good progress and it has been seen at least from the previous season too, where Newcastle managed to avoid and stay away from the relegation zone. But yes, considering Newcastle will get a more solid schedule next season, then Newcastle should recruit top players and to prepare for the second player who also at least must have good quality too. Because if Newcastle do not prepare well in this transfer window, then i sure maybe Newcastle will be chaotic situation later,, for example failing in the Champions League but failing also to compete in the top four in the English Premier League.
So at that let us hope to see if Newcastle United will be able to take home the arrangement and pursuit to end well in the 2022-2023 championship with their new formations.
