Arsenal again playing very poorly at the end of the season, as in previous seasons, but last season Manchester City overtook Arsenal in the table and became champion. This time Newcastle could beat Arcanal, cause Newcastle are only 2 points behind Arsenal.
Of the last 5 games, Arsenal lost 3 and drew twice and this is when Saka returned from injury, so most likely Arsenal have psychological problems, when the team can not adjust to the end of the season and starts to lose or draw at the most inopportune moment.
That's because Arsenal focus for last few weeks was UCL not EPL, they were in semi finals of UCL and giving best there. Now they are out from UCL and only thing they need in EPL is to finish in top 5, so they will play next UCL. Arsenal next two games are against New Castle and Southampton, they need to win at-least one of there remaining two games to stay in safe zone and play next UCL. To finish as second best team of this season they need to win both of there upcoming matches.
