I think that Arsenal are in a really desperate situation from now on. Because this was their biggest chance to keep their hopes very high for the Champions League. But they failed really hard against Newcastle by losing 2-0. We see now that Tottenham are two points ahead of them keeping the fourth spot. And Tottenham's last match is against Norwich. I assume they will get at least one point and qualify for the CL.
Arsenal chances to play in the champions league are now almost impossible, the negative result they got against newcastle has paved the way for Tottenham to locked the top four at the end of the season, although tottenham is only two points ahead from arsenal but it is impossible for arsenal to be able to seize the position The current top 4, equally have one match remaining, Tottenham have a lighter match than Arsenal and Tottenham only need 1 point to ensure their place in the Champions League next season.
Not almost but have close for getting last champion league ticket for Arsenal after losing from Newcastle United, if have magician if Norwich City can defeat Tottenham Hotspur last match and Arsenal win from Everton will be different. But almost impossible with Norwich City can defeat Spurs, how ever Spurs have many goals scored and draw or 1 point on next match have give champion league ticket next year.
