I still do not think that neither Chelsea nor Newcastle will be able to go to Europe, it doesn't seem likely. I get the point and I am not saying that it would be impossible to have something like that, of course it "could" happen and there is no argument that it would be impossible, I am just saying that it is unlikely and that's it. I get that we are in a stage where we are going to see the world get a better approach towards football rather than just spend money all thanks to this situation.
Because, we have seen City and PSG spend a lot and get league titles and then some, people assumed money just makes teams better and since Chelsea also had that with Abrahimovic and Newcastle had success last year, money looked like the only thing required. As we see this year, money is very crucial but not the only thing.
You are right, money can change many things for the better, but success cannot always be achieved because of money. Newcastle and Chelsea have not been good this season and it is not because they do not have enough money, but the squad depth they have tends to not be as good as other teams such as Manchester City, Liverpool and Arsenal.
Chelsea and Newcastle need to improve and they must do it. Improving the squad should be given serious thought instead of spending a lot of money on players who can't really make an impact, that's the big loss they've suffered this season. But perhaps, the tight competition with the top teams made teams like Chelsea and Newcastle fail because of the abilities of their coaches.
