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.
Getting a Champions League ticket is a dream of every football club and Newcastle got it so why are they too busy with a busy match schedule.
I think Newcastle just need to focus on the Premier League and Champions League for next summer so that their playing performance can be good without any physical constraints from the players.
Even though it is difficult to win one of the two leagues, at least Newcastle can show the world that they are worthy of competing with other big clubs.
