Their only goal now is to become champions of the Premier League and win the cup. I hope they win the cup this year.
Winning against Chelsea has obviously increased Arsenal's self-confidence and it's also helping the club to regain its mentality to compete till last match of the season. That being said, Arsenal's mentality has improved significantly since the club destroyed Chelsea with very big score and it was also putting pochettino in very difficult situation. It also indicated whether Arsenal is still ready for the title race at the end of the season consider that there are only fewer matches remaining and winning any game is a must in order to have big chance in winning the competition. Even though there is no chance that the city will be able to get three points from the remaining matches.
I believe this will be Arsenal's last chance to lead the competition since we are only having a few matches remaining. Arsenal players may always be seeing city playing the game soon caused by thisis the biggest obstacles for arsenal. It must also be cautious with Liverpool because the Reds are still consistently winning games and have the potential to reclaim first place. Manchester City still has a lot of unplayed matches.
It must be cautious when facing any club because winning the game is essential for Manchester City and yeah pep must always use the best squad in order to gather three points easily from any remaining matches for city.
