Maybe Newcastle United will be the new sensation of the new season. I think it's especially great about this team that they didn't spend a lot of money and therefore still finished 4th in the competition. If they had spent 500 million more they might have come 2nd. Arsenal were unstoppable in the first half of the season. There must have been a certain moment when Arsenal really started to believe in the title and it was precisely at that moment that things went completely wrong, the fairy tale seemed to end so beautifully.
Newcastle spend much last season, after then Arabic owner took over the club, for over many years they haven't been to Any European cup. But the take over has proven that every big clubs was once a small club, until a rich owner took over the club.
Arsenal and Newcastle are on the same scale of ranting now, both has not won any europen cup, But I'm sure Newcastle will win it before Arsenal. Newcastle is a big club already, and they can bring in any player of their choice just like every other elite clubs, because they have the resources to compete in the market.
Well, I quite agree with your opinion, and for your presumptions that Newcastle will win the European cup before Arsenal, well, I wont argue but will only say that the best team between the two win it first.
Arsenal played quite well in the just concluded Premier league games, they only started misbehaving by the time the game was coming to end, and that cost them their initial first position, they later ended up in the second position which is not quite bad, but over all, as a serious team, I believe they will go back to their drawing board and see how they can correct whatever went wrong in the course of their gameplay..
So when it comes to which of this two teams that will the European cup first, I would say that, only the future is truly sure of which team will achieve that first.
