Although still 1 point ahead of tottenham but it looks like arsenal position and their opportunities are starting to be threatened now, tottenham will face two bottom teams (relegation zone) and if we look logically it looks like tottenham will get easy points in the rest of their matches later, but not so As with arsenal which has to face two teams below it which are quite strong and are starting to experience a resurgence at this time namely newcastle and everton, newcastle and everton which are starting to rise now of course they will play very aggressively to win and I also think arsenal may lose points in the match against newcastle later, because as we know now newcastle is starting to be quite consistent and even they are starting to move up to the middle board after they have been at the bottom of the standings since the beginning of the season.
Oh of course, Arsenal now have to win all the games if they want to be in the Champions League next season. There are no more mistakes they can make because actually Tottenham have the potential to overtake him in the standings after only 1 point adrift. It's a bit surprising to see Arsenal's performance in that match, but this is a derby that is very profitable for Tottenham after Arsenal only played with 10 players.
Everton, who are actually not safe from the relegation zone, will probably be a big threat to Arsenal because they will definitely target a win to keep their chances of surviving in the Premier League next season. The same will be done by Newcastle because they have lost 6 points from their last 2 matches.
